Unfortunately, my room is TINY and almost square. I had a bear of a time getting it tuned and keeping some "life" in the room. Alas, I have a huge hole at 80hz (which I expected based on the math but have learned how to "hear" it and work around it.)
Since 99.9% of what I actually "record" is vocals or voice overs the most important thing to me is #1, an accurate room to mix in, and #2 a quiet and neutral place to capture said vocals. I do have a quiet enough control room to do acoustic guitars and I can mic a bass cab or EG amp but I rarely do that anymore. Most of my work is either for long time clients doing vocals, mixing those vocals in with the individual instrument tracks they recorded elsewhere or my own projects which are either all acapella or use all electronic instrumentation.
As for the computer, I use a (fairly old now) Dell server with a Xeon processor. Rock solid. I have never been one to mix "in the box" so I always mix down via the board. I really like the hybrid approach and the options is gives.
She ain't much to look at, but I get pretty good results.
