Out of interest, this company offers co-location in Media City for £35 per month, should we ever need it for mailpod. A fit PC should easily fit their space requirements, but our current server would not.
Co-location is basically where we pay someone to house and power our server hardware for us.

Also the fit-pc 3 is now more powerful than last time I checked. Current specs of their most powerful model:
1.65 GHz dual core 2GB DDR3 250GB with Linux Mint WiFi 802.11 b/g/n + BT 3 18 watts
Currently £379.35 all inclusive, though an additional HDD would be very prudent.
Just keeping you all up to date on options for the future :)
