I have an Intel Macbook, version 5.2. It has:
Intel Core 2 Duo, 2.13GHz
Nvidia GeForce 9400M
Mac OS 10.5 Leopard
It's a pretty nice laptop, everything works. I used to play Starcraft 2 on this all the time with decent FPS on low/medium settings.
I'm not interested in any trades, unless you have a nice Windows laptop. I'll try to post some pictures soon.
