Lenovo T500 i bought off ebay for 130+30 for oem charger. took it all apart cleaned and applied new antec formula7 thermal compund. It has 4gb ddr3, dedicated gpu, t9400 core 2 duo, 160gb hdd, and win 7 ultimate. great magnesium chassis for a rugged laptop. Its my take everywhere laptop and it should be great for tuning.
