A friend wants to buy my system, just the tower. How much does everyone think it is worth. AMD 64 4000+ @ 3.0Ghz Arctic Cooler 64 Pro 1Gb OCZ Platinum PC3200 220.127.116.11 MSI Neo 4 Platinum 2) Maxtor 300Gb SATA HDD's Lite-On DL DVD-CDR burner 16-48X X1800XT flashed to XTPE @ 720-840 Antec 1050B case with 550W PSU The whole system runs quiet. I have removed all my heatsinks and lapped them, on the CPU, GPU, Nfarce chipset, and Vregs on the graphics card. What do you think is fair if I redo his setup and move all his files and have a complete working system?
