im looking to put a more modern system into the shell of a G4 15" imac. itx or mini itx, thinking amd gpu. im limited to around 250-300w as im building a PSU for this and it needs to fit.

in reading i saw one guide that said up to 12th gen, another that seems to list work arounds for anything newer than 10th, lack of igpu support?? bottom line - what generation intel should i focus on here? i have a i3 12100 laying around but i dont need to use it if its going to be a royal pain.

what all should i know before buying things?

last time i did this was in 2007 on a dell laptop in college. cheetah iirc?
