Something I would like to do is get older PC’s, upgrade them and sell them. I have been seeing videos of guy’s doing it and it looks interesting. They buy older PC’s off of Ebay for 50-60 bucks and do some upgrades and then sell them. They usually buy old Dell OptiPlex office PC’s and upgrade them to be pretty decent budget gaming PC’s. Most of them are I5’s and the best ones to get are the latest Gen I5’s. You have to do your homework before buying! The parts are available and cheap. $65-70 dollar graphics cards that were top of the line and $2.50 dollar memory sticks.
Back 15 years ago I couldn’t buy one of those PC’s decked out but now you can deck one out to the max cheaply and play some truly fantastic games that won’t run on newer equipment.
I also see them buying lots of broken things like Switches. They may buy 6 listed for parts or repair for 75 bucks. They may be able to repair 2 to sell for 60 each and use the rest for parts.
This is just something I have been kicking around. I will let you know if or when I start!
