I have a Dell E6500 I'm looking to sell... I'm a little reluctant to sell it because it was a custom build with a 1920x1200 screen resolution. But it's got 4 GB of RAM, 500 GB Momentus XT SSD/Mag hybrid drive, Core2Duo T9550 (2.66 GHz), NVIDIA Quadro NVS 160M, 15.6" LCD.
The battery lasts for an hour or two (I've never really timed it) - but could probably use replacing or a bigger battery. Other than that it's in excellent shape. DVD RW with Lightscribe, SC card reader, PCMCIA, SD Card reader, E-SATA, Suspend Charge capability, firewire, wifi, VGA and Displayport. Pretty loaded.
How much are you looking to spend BTC wise?
