What I want to see is this thing fit 7 Nvidia Tesla T4 16GB cards in it. HP says it is possible in the data sheet.

Projects are fun. Do it if you don’t mind failing. Just keep failing until you get it right.

The setup is not ideal, I won’t lie to you. It could be better. But honestly, if it works for you, do it. There are so many things you can do to improve it and generally it will serve as a stepping stone to the next upgrade you see yourself making.
