i've been collecting home entertainment equipment for a couple of years now whilst living in rented accomadation so i've never really installed it properly.
so the time has come to buy a house (which i've actually just found out may have fallen through but we have to put a brave face on these things

)
and wire it all properly, because my girlfriend can't stand the wires

.
i've been thinking about it and looking at my gear thinking theres got to be some way of rigging it all up so its user (girlfriend) friendly, heres a list of my equipment
nec vt45 projector
xbox (currently used as dvd and media player aswell as games)
marantz sr5200 surround amp
kef kht 2005 speakers
cambridge audio universal remote
tv
pc
i would like to wire it all up so i can watch all av sources through the tv and the projector, listen to everything through the amp and get the most out of all my equipment but with the minimum amount of switches (which is the only way i can think of doing it). i would also like to make it so i can easily add more sources, so i can plug a dvd player in when i get one and my gamecube and other consoles in when i can be arsed to dig them out
i am on a limited budget because of the move but any suggestions would be greatly appreciated and much considered also any suggestions to good cableing practices because i want to hide all the wires would be great to
