The ssupd Meshroom S is not a revolutionary case, more accurately described as an evolution, or tweak of the original Meshlicious. There may be marketing or sales reasons to give it a different name - for example so that both cases can be sold alongside each other instead of retiring the original. Interestingly enough, the Meshlicious sells for more than the Meshroom S on the ssupd website. Even so, the price advantage over other, very capable SFF ITX enclosures is not as obvious as when the meshilicious launched, well over a year ago, especially as many brands have seen the benefits of ventilated metal panels instead of glass. Additionally, PCIe 4.0 ribbon cables are included far more often than not. There are several alternatives that offer more focused ITX engineering with a larger feature-set, some with 280 mm AIO support for the same or less money. Where the ssupd Meshroom S shines is that it manages very good thermals for a case of this volume, even without any additional fans and being a standing SFF chassis, taking up less space on your desk.
Internally, it's great to see plenty of tweaks and adjustments, offering a superior build experience over the original. No more sacrificed screw to install an SSD, an additional bracket for ceiling storage or the ability to install a 15 mm fan at the top for additional cooling - these are just some of the improvements the Meshroom S offers.
There are some oddities too however. The power button in the rear is a questionable choice, especially as there is room to include it in the top IO panel. Additionally, while it's nice to have the option, I feel ssupd is trying to push the reasonable limits of the case by marketing it M-ATX or ATX capable. While technically true, this presents an edge case forcing other compromises.
Overall, for the target audience, the Meshroom S has certainly retained its luster passed down from the Meshlicious, the new color options combined with general refinements set it apart from the competition. The Meshroom S is one of the best standing, SFF ITX cases you can grab today - especially if you are into 3 or 4 slot GPUs alongside 280 mm liquid cooling potential!
