Can't stop buying the wrong PC case. I thought I was buying a case that could contain two GPUs, but alas...I'm back up in the old case (which it turns out is actually more spacious and can hold an E-ATX board, even though it doesn't say it can), still with only one GPU, but I was able to put in the extra RAM, so I've got 112GB of RAM and 32GB GPU (an ancient Radeon V620, nothing fancy in this market). I was planning to have 64GB of GPU, but I'll need to buy a fourth case the size of a fridge.
