Ok a few weeks ago I bought a 2.8 500GB C2E iMac at a bargain at $1690.. I posted this on craigslist to see what I could get for it... (I don't need that much power and even using tons of apps at the same time I still have 1.5-2GB of ram free) I get an email from a guy who is offering me a Black 2.0 C2D Macbook, a 24" iMac C2D 2.16 and a 1TB Western Digital Hardrive.. would the following be worth my C2E 4GB 500HD iMac? Thanks!
