Last check on Spec if you don't mind 
Intel Core 2 Duo E6750
Gigabyte GA_P35C_DS3R
Corsair 2GB Kit (2x1GB) DDR2 675MHz/PC2-5400 XMS
Corsair HX 520W
Western Digital 250GB 7200RPM 16MB Cache SATAII/300
I tried to shave off the pounds where I could, so I opted for a 250GB instead of a 500GB HD as i haven't even come close to taking up my current 120GB and can always add another in the future if needed.
Couldn't get away from the good feedback for the Corsair HX PSU so chosen that, pretty sure it's more than capable to power the above spec (right?) aswell as a PCI-E X1800XT 256Mb which i'm re-using.
Motherboard seems a good buy for the price and has got good reviews from what i've seen.
So basically - the only thing i'm not 100% on is the RAM.
I will most likely never overclock any of it so I don't need the best overclocker, what i'm after is the fastest and most reliable at stock speeds for around the same price as the rest.
So some help on that before I order would be great, thanks.
