Yeah, honestly I’d be better off buying a studio. I’m just not used to not being able to upgrade the Ram in a device. Unfortunately, there’s a fairly legit reason for it, and many PCs are that way now.

I’d pull the processor and ram out build a mini pc out of that, toss this conversion kit in, and then use the iMac as a display for both the upgraded arm Mac and the pc, that intel should see performance improvements in a larger more traditionally cooled case, it probably needs repasting by now anyways.
