FriendlyPerson Good point, I've got a bunch of old computers too, like 20 years or so. Still fully working, alright to be fair a laptop battery only lasts 5-10 minutes after all this time so I have to disconnect it and run it on the grid at all time. And the old P-ATA drive is dead since long. Still, it has USB 2.0 so if I only find a 32 bit version of Linux it'll boot and run without issues.
I haven't bought used tho, those have been in my possession at all time. Any advice regarding buying used on amazon or eBay? It seems like a good idea if you can save money.
