https://www.techpowerup.com/264035/deepcool-rolls-out-matrexx-30-si-minimalist-m-atx-case DeepCool today rolled out the MATREXX 30 SI, a sober-looking minimalist Micro-ATX case for those who don't like to stare at the innards of a computer. Its design is characterized with opaque black steel side panels, an all-black interior, and a ridged front design that has slits between the ridges that serve as the front intake. The front-panel I/O is located at the top of this panel.
Inside, you get room for a Micro-ATX or Mini-ITX motherboard, a conventional ATX power supply, and plenty of storage options - two 5.25-inch bays, from which one is external; three 3.5-inch bays, and two additional 2.5-inch mounts. Behind the motherboard tray is 1.5 cm of crawlspace to route cables through. The main chamber offers clearance for graphics cards up to 25 cm in length, and CPU coolers up to 15.1 cm in height. Cooling options include one 120 mm front intake, and a 120 mm rear exhaust, from which the exhaust fan comes pre-installed. Front-panel connectivity includes a pair of USB ports and HDA jacks. We expect this case to be priced around $30.
I suppose if you don't like to look at your build this is the PC case for you. You can't really say too much bad about it for 30 dollars. I can think of maybe one advantage and that would be if you use this case for a PC build for small children. It would be more difficult to open the case and stick their fingers inside.
