I'm looking for the best value desktop PC for around £300-£400, ideally a i3 processor with 4Gb ram. No monitor is required, although if included at a good price, I can sell it seperately after.
It will be needed to run basic tasks such as web browsing, excel / word etc, and mainly used as a media centre in my lounge for watching 1080p high def movies (avi, mkv etc). It wont really be used to play games. HDMI output would be good, as would be 7.1 digital output (ideally via HDMI, although I'm not sure if this is available, otherwise digital coax).
Any suggestions would be much appreciated.
