I've already built my PC. It has an ASUS Z-270A motherboard, and intel 600p m.2 nvme storage. So because I have a m.2 hard drive and I didn't even bother to plug in my optical drive, the entire right half of my case is completely unused. I have been looking for a small case that supports an ATX motherboard but does not make space for hard drives and optical drive. Does anyone have any recommendations?
