I dont really have any skills i would consider useful, but im up to learn something as long as i dont have to work outside because im in Arizona and its crazy hot here. I would like to start small if possible.

Im 19 the 80s sounded cool but im not from that time period.

Ive thought about just doing a case swap and upgrading what i can but that dosent really seem worth doing. Also yes what i mostly have is optiplex-like systems. I have found some with a i7 on the other hand, the best machine i found came with a i7 and a 4vram nvidia card. Im mostly lost on what online marketplaces to list on.

I somehow dont have any macs, there mostly old office windows based computers. I have 1 imac with issues.
