Chosen Solution
I’m going to throw in. the towel and just reach out to some spare parts stores for items I need. For instance, as @danj said, see about getting a already fixed mac mini a1283 logic board; a drive for a powerbook g5; memory for an imac g5. Then mac pro parts for my upgrade. So where is a reputable parts dealer BESIDES Ebay ?
Sadly, this models parts are just hard to come by as well as costly as its so old. MacPartsOnline is one of the few that offers a logic board. Frankly, I would just locate a used system on line as it will be cheaper.
