Low power home server for <£200

[scoobyrichuk]

I'm going to build a home server for backup and media streaming, I want it to be as quiet as possible and have low power consumption. I have around £200 to play with and I'll be using FreeNAS so £200 doesn't include an OS. I Know that I don't need anything too powerful, at the moment I'm thinking of buying this:

Total = £191

I'm tempted by an Intel atom based setup due to the low power consumption but I don't know if this is possible within my budget. I plan to start with 1TB and would probably be adding another 1/1.5TB HD in the future, FreeNAS will be run from a USB Stick.
I'm new to server builds so any help is appreciated.

Thanks for all the info posted so far, I'm still not sure what option to go for yet as I've decided I'd like to be able to stream video to an xbox 360 from my server. I cuirrently use tversity on my own pc to do this and it works well but it's only available for windows. Is anyone aware of any other applications that are capable of transcoding videos in real time whilst streaming to a 360 (that work in linux)? I'm not sure that FreeNas (or any of the other suggested alternatives) will be capable of reliably streaming video to a 360 as I believe the 360 can be fussy about playing certain video formats...?

I've decided that I'm going to need something with a bit more power than an atom based setup if I'm going to stream to an xbox 360 with tversity. Also, going for a mini itx system is going to limit hard drive space massively and I'm thinking that in a few months I'm going to want add more hard drive space so perhaps a c2d/amd x2 based system would be better. I'm happy to run something 24/7 as long as it's not consuming significantly more than 100w (will cost me around 20p a day in electricity). It's going to have to be quiet as it will probably be located in my lounge somewhere (near thr router.) I'm willing to up my budget a bit if necessary, so far I have come up with this:

ASRock 4Core1600 (£40)
C2D e5200 (£50)
2gb DDR2 RAM (£17)
1TB WD Green HD (£75)
Akasa Zen Case (£30)
Xilence 420w silent psu (£40)
That comes to £250 without an OS, if I'm going to run tversity (which I'd like to as it works flawlessly with my current pc) I'm going to have to run windows (xp or homeserver.) I'm sure some people will think that I should use linux or something based upon it but I'm thinking that for someone with no prior knowledge of Linux perhaps a Windows based system would be the best option. I'm hoping to undervolt the e5200, this should hopefully mean lower power consumption and less noisy fans being required.
Any comments are welcome...
