check out gyration for wireless mouse and keyboard. they work 30' and much better than logitech's wireless. as far as what SSearchVT said, i'd go with a Media 2005 machine. Noise from the PC wont be an issue if you search for the right hardware. look into the Antec solo tower with their EarthWatts PSU's. the tower has rubber bands inside so the hard drive wont vibrate. their PSU's are 85+ efficient and have low noise. i've stuck with coolermaster for CPU and case fans, but i know the more expensive ones are quieter. make sure you use artic5 thermal past on your CPU to keep the temp down about 5 degrees lower, which will help the CPU fan spin at a lower RPM.

for audio cables, i just hooked up a surround sound setup last week in the president's office. we actually used CAT5e cables, and got CAT5e --> RCA jacks from blackbox. punched down the CAT5e on the jack and plugged in RCA cable to the reciever. i know it's not as good as optical, but it's low cost if you're looking to mount speakers far away.
