My new build!

[RLP06]

Hi guys, here is my new build:

AMD Athlon II X2 240 @ 3.4ghz
Gigabyte GA-MA78LM-S2H
G.Skill 2GB Kit (2x1GB) DDR2-800 4-4-4-12
WD 500GB Caviar Blue
Antec NSK1300 SFF Case

What do you guys think?

Was originally looking to put together a budget computer for using XBMC on, but has turned out superior to my current desktop which is an C2D E4400, haven't decided which I want to be my primary PC now, lol.

I have 2 questions for you guys:

1) How much do you think it'll cost me in electricity to keep this running 24/7 (300W power supply)
2) Do you think I should get Windows 7 64-bit? I've never tried a 64-bit OS before.

if the psu will be use at 100% it will cost you something around 10-20$ a month, depends on how much a kw you pay , but the 300w is only a rating, your PSu use only the amount your PC need, less of course a certain % lost in the components.

What % of the PSU is actually used on average when your computer is just sitting idle? I don't have many components in there really.
