For sale is my computer I built for gaming/engineering work. At the time of purchase I selected only top of the line parts which is one of the reasons it is in such great condition today.
Antec 900 Cold-rolled Steel Case - 4 fans and built in rubber grommets in the back for water-cooling tubes
EVGA 780i motherboard (EVGA offers lifetime warranties on their products) - SLI ready
Intel Q6600 Core2Quad processor - One of the highest rated CPU's with the 775 socket type
Kingston RAM DDR2 (2X2GB) Model # KVR800D2N6 - Top rated RAM
EVGA GTS 8800 - Dual DVI ports
Antec TPQ-1000 - Modular PSU
Acer AL1916W Monitor with a 3-section desk mount - I dont have the original stand that came with the monitor, but honestly one of the best investments I've ever had was a 3-section desk mount. The mount can either be clamped onto the desk or screwed directly into the desk.
I also have a variety of cables to sweeten the deal if need be (KVM switches, SATA cables, USB hubs, etc)
