Maybe $100 if you can get it. Mainly just a lot of outdated and useless hardware.
The CPU on its own is about 7 years old, working perfectly fine though. The GPU is about 4 years old, still working pretty well, but it's a workstation gpu. As for everything else other than the drives, it is getting dated, yes.. especially the fans, which I will be changing soon
