Hi, it’s that time again when I start thinking about upgrading my RIG to something better.
At present I have,
CPU AMD XP3000+
Fan Coolermaster Aero 7+
MoBo ASUS A7N8X Vr 2.0 ( Socket A )
RAM 2Gb Corsair XMS PC3200
HD 160 GB WD Caviar Special Edition 8Mb Cache
SATA 1
PSU Tagen 580watt 18db SLI
VGA Gainwood 6800GT

I will be selling all the above apart from the PSU.

The proposed set is
CPU` AMD Athlon 64 X2 Dual Core 6000+ 3.00GHz
Fan ! ? not sure yet
MoBo Asus CROSSHAIR nForce 590 SLi (Socket AM2) PCI-Express DDR2
RAM Corsair 4GB DDR2 XMS2 PC2-6400C5 TwinX
HD now, I am not sure what to do on this
Do I have a WD raptor 74Gb for C drive or 150Gb Raptor for Program drives, or raptors for both drives !
Or WD Caviar RE 500GB 5000ABYS SATA-II 16MB Cache for programs, and 160Gb Caviar SATA II 16Mb cache for C drive.

VGA some 7950 for now
Case All the above set in a P182, does
any one know if I can get a Side window this ?
