Mini-ITX system builds have become big business as more and more consumers are looking for compact and stylish PC solutions for their home office and living room. The InWin B1 certainly fits the bill. The InWin B1 mini-ITX case has been introduced back on 2020 with a minimalist look that can be used vertically or horizontally. Some of the main features of this Mini-ITX case was the extremely small footprint, and the vents that are incorporated into the exterior design of the case. These two features make this box perfect for work from home office or some not too powerful gaming equipment. While the little B1 offered a wooden upper panel a few weeks ago, now InWin brings a new variation with the B1 Mesh, which quite logically offers mesh on the top. A very different approach for a case which is now offered in three different versions so that everyone finds something to suit their tastes, but also the cooling needs of the configuration which remains limited to 60 mm for the processor radiator, with an 80 mm fan present by default on the side (or the top if the case is installed vertically via its support supplied as a bundle). While the glass looks great, it does lead to some relatively high temperatures, and while these won’t come close to putting your PC at risk, they do come with the annoyance of high fan speeds. Inside, the power supply is still 200 W with an 80 PLUS Gold certification. No PCI bracket is present, and we will therefore opt for a processor with an integrated graphics part. As for storage, it is installed on the back with two 2.5" slots, plus a cutout in the motherboard support for quick access to a possible M.2 slot.
