Arguably the most interesting one is a modular case. It comes with, we believe, 8 corners and 12 columns.Editor's note: This was originally published on May 20, 2025 as a video.

The cases are the MF series, with the largest one being the MF600, which we assume translates to “Motherf***ing 600.” There’s also the MF500 and the smaller MF400. Initially, Cooler Master is basically going to be selling pre-configured models. Eventually, the company wants to allow people to customize the case on their site and have it assembled and shipped from around the City of Industry. It’s pretty cool as it’s a fully modular approach.The side panels are secured to the case via magnets, which is actually a nice touch. Internally, the MF600 we saw came with 3x140mm fans on the front and 1x120mm fan on the back. The motherboard tray is pretty standard for the most part. Exceptions include a rail system that provides numerous holes for screws to go in, which allows Cooler Master to reconfigure things. Inside the case towards the back, there’s also a rail system, which forms bits and pieces of the motherboard tray that allow for more customizability. Cooler Master has been kind of on-and-off in the DIY space over the years where they’ve had some really big wins and some really big losses. They were also kind of absent for a while, but these MF cases represent a better showing from what we’ve seen in a while from the company. According to Cooler Master, a pre-configured MF600 is supposed to cost $200. We expect to test and review the case. The MF500 is supposed to go for $165 and includes 2x200mm fans in the front and 1x120mm fan in the back. The smallest MF case, the MF600, which is a very large micro ATX box, is going for $150. In terms of fans, it has 2x120mm ones at the bottom coupled with a 1x120mm fan in the rear.  Cooler Master also showed off different panel types they’re experimenting with. One of them included a facade-style stone. One of the pre-built MF cases we looked at had stuff flipped around in an inverted layout. One of the benefits of its rail system allows the case to have a bar that screws in which can support the GPU. Looking into this system, you can see that the PSU is at the bottom next to a bottom intake fan. Updated Cosmos Visit our Patreon page to contribute a few dollars toward this website's operation (or consider a direct donation or buying something from our GN Store!)

We have some criticisms of its execution, but overall, it’s an interesting idea.  The way the baffles are designed, Cooler Master is trying to bring air straight in through its channels. There’s a channel for the CPU that exposes the fin stack and Cooler Master's V8 CPU cooler. It conveys an idea similar to an engine cover. The GPU has a separate baffle beneath the CPU one. The company is trying to isolate air flow. In theory, this should work well and we would love this idea applied to more affordable cases, like the MF series, especially since they’re already kind of configurable. Looking at the back, fans can be mounted on the rear, which can help pull air out. We also saw another variant of the Cosmos case running liquid cooling with a distro block. It was coupled with 4x180mm fans and a “720” radiator, which pulled air into the case. Unfortunately, the air is blowing straight into the wall of a motherboard tray, but Cooler Master says the plan is to pull the air up and out of the case with additional 180mm fans on the top and to move the PSU towards the bottom of the case. Looking closer at the front of the special edition of the Cosmos cases, we can see the NVIDIA DGX shroud, which Cooler Master manufactures. It’s essentially like a sponge-like mesh. The special edition of the Cosmos doesn’t have a price yet, but the non-special edition variant is supposed to be around $400, which is before any potential tariffs. Cooler Master CoolersCooler Master showed off some CPU air coolers that had some 3D heat pipes, which had more heat pipes protruding from the center. The company also showed off its V8 cooler and a full-metal fan. The fan’s blades and frame are both aluminum.  Cooler Master Elite Series CasesCooler Master does some really cool sh*t but has a branding problem. For instance, the company’s “Elite” series cases, shown in the image above, are actually budget cases. From left to right, we believe they are called the Elite 482 ($50), Elite 600 ($65), Elite 490 Wood ($50), Elite 691 Wood ($60), Elite 693 ($60), Elite 692 ($70), Elite 302 ($40), and Elite 502 ($60). Our advice to Cooler Master here is for them to unf*ck these names.Most of the Elite series cases don’t come with fans with the exception of the Elite 302 and Elite 502, which come with 3 ARGB fans. MF360Next up are Cooler Master’s MF360 cases, which conveys that you can see inside the case from all sides. While it’s going to have some thermal challenges, to give the company credit, it’s actually really good looking. The MF360 is a showcase fish-tank style PC that you can see through from both sides. Inside the case, we saw a distro block and tubes routed through on both sides.Cooling XThe case in the image above, which goes by "Cooling X,” and uses the company’s new MF frame system. If you look at the corner, you can see the individual columns. At Computex, we saw it as a pre-built system.The top of the case has a magnetically attached panel, which just pulls right off. The panel itself provides really good porosity and the material is pretty nice. Removing the top panel exposes 2 offset fans. The back fan tries to pull in air with the front fan trying to exhaust air out of the top, which is why they’re offset. That’s kind of cool to see.  Cooler Master FansCooler Master showed off all-aluminum fans, which include the blades and frame. The MF120 XT is a 120mm model, is supposed to be $35, and the company says it goes up to 4,000 RPM. The fan’s RPM can also be button-controlled via an external remote and it uses a dual-ball-bearing solution. Cooler Master’s mixed fans, which use plastic blades coupled with an aluminum frame, come with fluid dynamic bearings (FDBs). The clearance between the fan blade tip and the frame is important as the smaller that clearance is, the better performance you get. The major downside is that as the fan ages, it can start to clip the interior of the frame. Having it too close can also negatively impact yields. The solution to this is LCP, which is incredibly expensive, or metal, because it doesn’t deform, but that’s also expensive. Right now, Cooler Master says it’s about a .8mm distance, which is pretty good. The company is targeting 0.6mm by the time the fan launches. Cooler Master Video Card Shroud Grab a GN15 Large Anti-Static Modmat to celebrate our 15th Anniversary and for a high-quality PC building work surface.

(or consider a direct donation or a Patreon contribution!)Cooler Master also showed off some video cards, which is not something the company is typically involved with. Cooler Master created a GPU shroud with adjustable slats that can accommodate 15-30mm fans. This solution is geared towards pre-built PCs and isn’t planned to be sold separately.Examining one of the fans, we saw a standard 25mm-thick fan, which Cooler Master’s GPU shroud solution can adjust to via different notch options.Cooler Master is also using a vapor chamber, which is supported by 8x8mm heat pipes running through the shroud and a gigantic fin stack. In total, it weighs almost 7 pounds (3.2 kilograms).Cooler Master claims that, in terms of cooling, it performs similar to the 4-fan Astral solution at lower noise levels, but we don’t have those numbers. With 4,000 RPM fans running on a 600-watt heat load, Cooler Master claims a 5090 will run at about 49 degrees C or so for the GPU.

You can do PC stuff on Bazzite (run Office style apps and any other app you'd use on a PC). Steam OS, at least on a Steam Deck, while it does have a desktop environment, is kinda limited in what you can really do. Also, Bazzite isn't the only Linux distro with a handheld mode. Nobara and CachyOS are also great choices. Bazzite and Nobara also have Lutris and Heroic Game Launcher installed by default, Cachy also has them available but you need to just install a gaming package (literally click on a couple things after the initial install).  maximumzero Member Oct 25, 2017 24,842 New Orleans, LA Hopefully someone gets this up and running on PCs.   Dinjoralo Member Oct 25, 2017 11,725 PianoBlack said: Interesting, I guess you'd do it for the power management / some system QoL stuff like login?

w/s/l? Microsoft closes 9-year-old feature request, open-sources Windows Subsystem for Linux WSL has also recently added official support for both Fedora and Arch distros. Andrew Cunningham – May 19, 2025 1:49 pm | 23 Credit: Microsoft Credit: Microsoft Story text Size Small Standard Large Width * Standard Wide Links Standard Orange * Subscribers only   Learn more Microsoft's Windows Subsystem for Linux has become an important tool for developers and power users since it was introduced in the Windows 10 Anniversary Update back in 2016, giving them access to a built-in Linux command line and Linux applications from within Windows. The company has steadily improved WSL since then, improving performance, making it easier to install and use, and adding features like GPU and audio support. But today as part of its Build developer conference, Microsoft announced that it would be making almost all of WSL open source, closing the very first issue that the then-new WSL project attracted on Github in 2016. "WSL could never have been what it is today without its community," writes Microsoft Senior Software Engineer Pierre Boulay in the company's blog post. "We’ve seen how much the community has contributed to WSL without access to the source code, and we can’t wait to see how WSL will evolve now that the community can make direct code contributions to the project." Only two elements of WSL remain closed-source for now: an lxcore.sys kernel driver used for WSL 1 (the initial version of WSL that is still supported, though new installs default to 2019's WSL 2); and the p9rdr.sys and p9np.dll files that handle filesystem redirection from Windows to Linux (in other words, making it so that Windows can easily access the Linux filesystem). Microsoft didn't close the door to open-sourcing those components but also didn't say if or when it planned to make them open source. Though WSL uses some of the same technologies as virtual machines, WSL's speed, low resource usage, and integration with Windows makes it much more seamless to install and use than traditional virtual machines that maintain more separation between the host and guest operating system. Around the release of Windows 11 in 2021, Microsoft made WSL something that was installed and updated via the Microsoft Store rather than something built into the operating system, making it easier to add new features without requiring the potential disruption of a full Windows update (and also possibly making it easier to open source the code without posting source code for other parts of Windows). This isn't the only major improvement Microsoft has helped to release for WSL recently. Earlier this month, the company announced that Fedora is now an officially supported WSL distribution, joining Ubuntu (still the default) and a number of other distributions. Arch Linux also became an officially supported distribution back in April; both Fedora and Arch are taking advantage of changes Microsoft announced last year to make it easier to build new WSL distributions. Windows users can install WSL by choosing a distribution from the Microsoft Store or by opening a command-line window and typing wsl --install. Users can install multiple distributions at once and switch between them based on what they're running or testing; typing wsl --list --online at the command line will also show you all of the distributions that Microsoft officially supports if you don't want to use Ubuntu.

Linux Windows 11 dual boot to finally play well as Microsoft fixes nine-month old bug Sayan Sen Neowin · May 15, 2025 01:48 EDT It is known that Patch Tuesday updates can often lead to big issues and something just like that happened last year in August. The security update had broken dual-booting Windows 11 and Linux systems as GNU distros like Debian, Ubuntu, Linux Mint, Zorin OS, Puppy Linux, were all affected. A couple of days later, Microsoft provided a slightly lengthy workaround that involved tweaking around with policies and the Registry in order to fix the problem. The company also explained that the root of the issue was a buggy SBAT (Secure Boot Advanced Targeting) implementation in the Windows 11 August Patch Tuesday KB5041585. For those who may be wondering, SBAT helps block outdated and potentially vulnerable bootloaders by checking the Secure Boot DBX. The Secure Boot DBX is a database of blacklisted UEFI executables. Microsoft explained: After installing the August 2024 Windows security update, (KB5041585) or the August 2024 preview update, you might face issues with booting Linux if you have enabled the dual-boot setup for Windows and Linux in your device. Resulting from this issue, your device might fail to boot Linux and show the error message “Verifying shim SBAT data failed: Security Policy Violation. Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation.” The August 2024 Windows security and preview updates apply a Secure Boot Advanced Targeting (SBAT) setting to devices that run Windows to block old, vulnerable boot managers. This SBAT update will not be applied to devices where dual booting is detected. On some devices, the dual-boot detection did not detect some customized methods of dual-booting and applied the SBAT value when it should not have been applied. The problem has been resolved this week with the latest May 2025 Patch Tuesday under KB5058405. This also happens to be the first Windows 11 Hotpatch update.

What just happened? Valve recently announced an alternative to the Steam Deck compatibility rating system aimed at third-party devices. The new SteamOS Compatibility labels work slightly differently but should provide users with vital information for each game as the company moves toward a general release for the gaming-focused Linux distro. Users who install the SteamOS beta on the Lenovo Legion Go S and the Asus ROG Ally should begin seeing new compatibility ratings on Steam store pages in the coming weeks. The new labels provide basic info regarding what happens when booting a title on Valve's Linux-based operating system. The Steam Deck verification system is a vital component of the Steam Deck's success, informing players which games run smoothly on the handheld gaming PC. The system is now so successful that major developers often optimize PC games to receive Valve's green check on their Steam store pages. On non-Steam Deck devices, a blue check will appear instead. Every Steam Deck Verified title will receive a marker saying "Successfully runs on SteamOS." However, users should note that the label has no bearing on performance. It only confirms that a game's engine and middleware, including anti-cheat, fully support Valve's Proton compatibility layer. Users will also sometimes see warnings for games that require internet connections during initial setup or include launchers that require mouse input. Valve estimates that around 18,000 titles will immediately receive SteamOS Compatibility checks when the system rolls out. While SteamOS will eventually become available for more handheld gaming PCs, the Legion Go S is currently the only third-party device that officially supports the OS. Lenovo is set to begin offering the handheld with Valve's OS pre-installed in the coming weeks for $150 less than the Windows 11 version. // Related Stories SteamOS has been the Steam Deck's primary advantage over Windows-based handhelds. Although devices like the ROG Ally X are more powerful, SteamOS runs many games more efficiently and is easier to navigate on a small screen with a controller. The Linux distro could surge in popularity on other handhelds, but a general release will likely complicate per-game optimization. Speculation has also spread regarding SteamOS' potential on desktops or other form factors and whether it can challenge Windows in the PC gaming sector. Recent reports indicate that Valve is preparing three more SteamOS devices: a standalone VR headset slated for later this year, a true successor to the Steam Deck that lies further out, and a mysterious "Fremont" project that could be a set-top box. The headset and Fremont will port SteamOS to Arm.
