Well i built my first actual rig just a couple months ago. Ordered parts off of newegg tigerdirect and frozencpu.com. Heres the specs:
-Acer 23" HD monitor
-Evga 750i SLI ftw motherboard
-4gb of ddr2 mushkin blackline RAM
-Intel core 2 duo E7500 overclocked to 3.4gHz
-Two Nvidia Geforce 9600GT's in SLI
-500 Watt Antec power supply
-Cooler master V8 heat sink
And its all wrapped up in a Cooler master storm scout case. Its a great rig and very fast. It just crushes through everything I throw at it.
