Figure I'd toss a thread to start this since my girlfriend has given me full reign over her last two PCs and didn't have really anywhere else to post it.
Top PC is her old main system, which after some digging had a Phenom II X4 955 with 8GB of DDR3-1333 and a Radeon HD 5850; something I thought was kinda neat. We booted it up and found two ancient installs of Kubuntu and Debian, probably that hadn't been touched since around 2012 (if file dates are anything to go by) and the clock was rather close to the current date and time.
I haven't delved into the bottom PC, which was apparently originally a file server she had, but the most I know is that it's an AM3 platform system, which will be fun to figure out what specs it has; at some point I'll probably repaste the Phenom II and maybe the 5850 and repurpose it.

Lots of old music and memes from 2010, some old game installs, and some other stuff. Really cool find. (screenshot taken with capture card via OBS)
What other cool stuff have you dug up and looked at? Could be anything from a PC you found at a local thrift store, thrown out, in your closet, or otherwise!
