Refurbished Dell Optiplex 3020 - $170
I'd rather not incur the $50 in fees to return it, so if you're in Kitchener / Waterloo area, I'd love to get it to you for $170.
I have opened the case and removed parts, but have put them all back in and ensured that it boots.
I have not installed anything, and the keyboard is lightly used.
Edit: After some posts notifying that me that I haven't provided enough information, please find info here:
