Not sure if this is the right place , but I'd thought I'd pick the brains of the experts here.

I have an HTPC that I'm retiring, but I was thinking of using the parts, changing the case, adding more drives, and making a media server because it would save some money. My worry is that the parts are an overkill, and will suck to much power. These are the components:

Intel Core 2 Duo E8400 Wolfdale 3.0GHz LGA 775 65W Dual-Core Processor
GIGABYTE GA-E7AUM-DS2H LGA 775 NVIDIA GeForce 9400 HDMI Micro ATX Intel Motherboard
CORSAIR CMPSU-450VX 450W ATX12V V2.2 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
ADATA 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model


Any advice would be appreciated (on whether it would cost too much to run, or even on what case to get that isn't too big). Thanks.
