Second the Node, very portable, quiet. It is a bit difficult to assemble though....

A current favorite among beginner Mini-ITX builders is the CoolerMaster NR200.

It's a bit big compared to other small form factor options(still smaller than midtower cases) but the hardware compatibility is great!

I manage to fit in a 5950x CPU and 3080 GPU with just an air cooler and it's working without thermal issues.

Indeed, the case is good, but they should have written better documentation.

I have found out I needed to unscrew the small front I/O panel PCB when removing the back side of the case. Then reattach back once the panel is clipped in. http://const.me/tmp/node202-front-panel.jpg
