I just got myself a 1.25GHz Lamp but I don't know if it's a 17 inch or a 20 inch. Got it with a beastly old XPS laptop, it works but the hard drive seems to be dead.
A guy who used to do PC repair for me had it. The laptop's a XPS M1710 with a 2.33GHz Core2 Duo and 4GB of RAM, should make a great gaming machine for older PC games.
Is that model 1920x1200 and 7900GTX go 512Mb? If so its a nice setup, but you would have to use real old games for that native resolution and GPU combo.
I found out that the old Thinkpad HD sleds will fit in the MacBook so I installed OSX 10.6 for now. Was reading somewhere that 32bit Linux Live CDs have issues with booting on the Macbooks and you can't boot 64bit OS.
I have 2 others, one of which is the original (pre 7000 name with T&L). This one was on ebay listed as the AGP model and only cost around $11 shipped.
