As title really, I was thinking of -
Athlon x3 435 ~ £62
Asus mobo M4A78STD-M ~£71
Crucial Ballistics DDR3 1333 2x2Gb ~£94
Cheap case ???
520Watt Seasonic £70
Pioneer dvr ~£20
Samsung F3 500Gb ~£40
Windows 7 HP OEM ~£80
LG LED Monitor E2250v ~£159
So as you might have guessed I was basing it loosely around the cheapest iMac with the 500Gb hard drive.
But, any sensible adjustments for cheap 'bang for buck' system.
