I'm looking to get a nice small and quiet machine for the living room to receive games streamed from my main computer in my room. I'd really appreciate some help with creating a build from you tech Gods. I have a budget of £250 however this can be stretched to accommodate whatever extra is needed. I don't need an OS as I intend to run Ubuntu on it and I don't need any peripherals. I have no preferred retailer but just try and keep it to within the UK :P.
Thanks in advance!
(Please tell me if I need to add some extra info.)
