Hi, Brandon!
Your post is really cool. I've been following mini PCs for a while now, hoping to find something really good with the maximum possible RAM. I was excited by your information about possible 64GB sticks. However, it's still something that's going to be released and the boards would need to have their BIOS updated to be compatible, which may or may not happen. At the moment, the MS-01, Core Ultra, and now the all-powerful 7945HX, which previously also had the 7940HX, are the ultimate mini PCs that can currently be assembled with up to 96GB of RAM. However, I'm also analyzing the Erying kits with 13900HX options with 4 RAM slots that can go up to 192GB of RAM. Currently, I think that would be the best mini PC or micro ATX that I could assemble at the moment. There are just no reviews of the Erying kits with 4 slots on the market. I'd have to buy them blindly to test them out.
