Compactness, appearance, the whole body is made in a grid)) the possibility of any location of the button module (power on, reboot and usb) in the photo in the standard it is on the right, and I placed it from below, dust filters (left, top, bottom) the possibility is so small case to put an ATX board, removable plugs for output ports of a video card and (or) other peripherals, the ability to put 6 turntables (3 blowing, 3 blowing, one from the left side of the case, 2 from the top, 2 from the bottom and one from the right side of the case up to 140 MM ! !) you can even put a 3-section dropsy, but you need to sacrifice one turntable for blowing from the right side of the case), there is a lot of space for managing wires, I don’t know if it’s a minus or a plus, but you can put either 2 hard drives (full-size) or 4 ssd (there are only two fasteners, you can put either 2 ssd or one hard one on one) for me this is enough, but you can cheat and place it not on the ssd fastener, there should be enough space. A video card 160 in height, 270 in length should stand up (if the power supply allows), my ATX power supply allows you to put 300 mm, maybe even 320, I don’t have such a monster, so I can’t check how it will be, and even if such you take the body from you, it is unlikely that you plan to shove such a mutant)))
