I have a used Mac Mini in mint condition but I'd love an MPC 2000xl. The Mini has a 1.83Ghz Core 2 Duo, 2 gigs of ram, an 80gig hard drive and built in airport card. Let me know if you are interested.
Definitely be a deal if you had the newer one. You can get a decent amount for your mac mini online. If you sell it, take a look at the 2000xl's I have for sale and see if we can make a deal on something.
