Yeah, I did bear that in mind, but I think there are two conversational directions going on here: "I want an SBC that can drive 8K video for $reasons" and "wow, a $400 arm64 desktop that just needs more RAM to be worth the hassle". I'm in the 2nd camp, and it wouldn't be a dealbreaker for the first camp unless using DIMM chips on an SBC is somehow cost prohibitive. I can believe it is, because hardware markets are weird, but if they could charge me $10 extra to use DIMM slots on that board, then they'd have my money because I could pack it full of RAM and not bother them about it
