Hey folks, any comments to be had on the Mac Mini #1.66GHz Mac mini (MA206LL/A) ?

Found it on craigslist locally for sale, been upgraded to a Gig of RAM, supposedly is a Core Duo (Dual core ? Having been an AMD user for years I"m not too keen on Intels naming strategy) sports an 80 gig HD and has a SuperDrive, anything I should look for as far as issues when I go to look at it ? thanks in advance ! (And oh yes, it'll be upped to Leopard if it does come home)
