Yea.. it's XP... but not much is worth salvaging... it was a ~$300 barebones dell package when they bought it... so you can probably imagine it's a little outdated... I have an old XP disk from my previous computer... will probably just use that. I appreciate the build, I emailed it to my mom... she has no idea what it is, but the price fits what they were going to spend on a lesser system..
