I wanted something for the kids to play fortnite on.
I found a used HP office machine (not sure of the model #) on craigslist with a I5 3470 and 4gb ram for $50.
I found a 128 GB inland ssd for $10
I found a used antec power supply for $5. All the reviews on this psu say that while it's ugly, it's a workhorse and lasts for years
The rest I got on ebay rx 470 4gb for $74 500gb hard drive for $10 4gb of ram for $10. ( I found a matching stick to what was in there and luckily it's running in dual channel.
$160 total to get the kids off of my computer.
