Proposal for making a Teenage Engineering computer-1 -like case for Raspberry Pi

What is the proposition for this case? With this much volume i'd be looking for the ultimate pi 5 that has:

1) Modular water cooling option (probably in the bottom)

2) UPS system middle

3) Easy mount of pi5 and NVME in the top

4) Easy way to keystone the gpi and other ports to a convenient shield on teh back ?
