New to this, so please be kind
I am looking to build my own PC. Not really needed for gaming or overclocking, just a good quality PC for the home.
Will be used to stream video / pics to my Xbox 360 and take video from my Video Camera. Runs Office and Sage etc.
Here goes:
LG GSA-H66NBAL 18x DVD±RW SATA Dual Layer ReWriter (Black) - OEM £18.99
Intel Core 2 Quad Q9450 LGA775 'Yorkfield' 2.66GHz 12MB-cache (1333FSB) Processor - Retail £219.99
Corsair 2GB DDR2 XMS2-5400C4 TwinX (2x1GB) £27.99
BFG GeForce 8400 GS 512MB DDR2 HDTV/DVI (PCI-Express) - Retail £35.99
MSI P7N Diamond nForce 780i SLi (Socket 775) PCI-Express DDR2 Motherboard with Free Creative X-FI Card £159.99
Antec Sonata Plus 550 Quiet Midi-Tower Case - NeoPower 550W Modular PSU (Black/Silver) £84.99
Hitachi Deskstar T7K500 500GB SATA-II 16MB Cache - OEM (0A33437) £58.99
Total: £625.92
Any glaring mistakes?
thanks for any help
