Phanteks PH-ES121XT_DGS01 Evolv Shift XT Premium Aluminium Galaxy Silver Expandable Mini-ITX Small Form Factor Desktop Chassis

The case comes with a single disassemble sheet that easily explains how the case is opened and taken apart with the case being just as easy to reassemble once you have finished building it. The quality is great and sturdy. There are about 3 screws with the rest being clips and slots with the parts sliding in or out. It makes for a very compact system with the potential for a lot of power.

I do have a few problems such as the riser cable needs to be clipped into the motherboard and its a rather tight bend on the cable. The other is the cable that goes into your power supply which I had to do an uncomfortable bend to it.

Not that the cooling problem is the case alone but unless your m.2 drives are stacked on the front of the board whatever drive is at the back of your motherboard will run hot. This might be fixed by adding a few fans for extraction at the top. I have seen smaller systems than this but as far as ITX goes I would say this is up there with the MSI nightblade from 8 years or so ago.
