SFF's new case?
The limit height is 145mm? Although there are some regrets, but at least I can install the bequiet dark rock TF and U9S in it(Don't forget 7980xe and X399 itx in the future,it still has a some possibility).
hoped that all aluminum and anodic oxidation (Custom-made ) options can be selected.
Finally, hope you have a portable bag.(I have bought the portable bag of Ncase M1, hope I don't need to buy a new one.)
Besides, hope you have a plan for compact ATX case.
The main reason for shrinking case should be portability. Second is personal preference,and the upper limit of this size should be ATX,because over ATX can not be portable.
Jonsbo C3 (old version) is a good example(yes, it can install ATX). In addition, the modularity of bequiet is also worth learning.
I just discovered that Streacom and SFF don't seem to be working together. Still looking forward to the new cases of SFF and Streacom
