1st, a projector is an awesome use of space, much more epic, but cannot be used very well in the day with the sun out. If she wants to watch her soaps, then a TV is probably better. We don't do more than 2 hours of tv every few days. Especially nice is if you put the screen over a large window or patio door. I have 105" diag screen and it doubles as a sun and privacy shade.
2nd, as for the computer, I had the same problem. However all i had to do was make an effort to fix it by installing some more high quality fans, and she has gotten used to the white noise it creates. Over time, spouses become more "domesticated" on both sides. You learn to forgive many things that would drive single you up the wall.
As for all those saying "use your spare room". You all are some rich motherfuckers! Maybe ill take the wife out in my spare car as well! Or there's always the spare boat. Ill just use some of that spare money to do it!
