You can probably do whatever makes most sense for your room. My projector has a 35' cable run back the equipment stack (in a completely different room) and I'm running a 25' KVM extension cable to use the keyboard and mouse. (So, in my case, the wired keyboard and mouse are quite close to the projector, but all are quite far from the computer.) I've got a wireless keyboard on order, but the above setup has been working smoothly for 18 months.
Probably best to setup the room however works best for the room and just buy/build the cables you need to make that work.
