There seems to be an even smattering of PC versus PS3 players, or perhaps there are slightly more PC players, and I'm curious where do you play video games in general (and this one particularly). There are good arguments for the console because you can sit on your couch/easy chair and play, and there are also those who are set up so that their PC is connected straight to their TV so they too can enjoy the cushy goodness of the living room.
I tend to be more of a computer desk kind of guy. In fact, I would say I'm obsessed with finding the perfect layout for my desk. I've read all kinds of articles, researched what others have done, and then drew up and built my perfect computer desk. It's nearing completion, I'm finishing the trim now (still need to stain and varnish one more piece) and then I will be making drawers for the center shelves (see below pic).
I invested in a very nice office chair so as to have maximum comfort. The far right monitor is small and is used for chat windows, ventrilo, etc. The next one to the left is my main gaming monitor, the PC that is between them is my gaming rig. Next to the left of the center shelves is my multi-purpose monitor, on which is displayed my Mac Mini's video as well as anything that is hooked up to the 4-port KVM. Lastly I have my iPad mounted on my other monitor arm for easy access while working, it is affixed with heavy duty velcro so I can remove it easily.
I love seeing what others have done, if you feel like sharing please do
Comments and critiques are also welcome, I tried to fit everything into my design that I could, but there is still some more work to be done. I have some lighting (other than the fluorescent lights above the monitors) that still needs to go in, and I'm still deciding the best way to arrange my decorative items. I have a fairly large Final Fantasy memorabilia collection that I'm contemplating moving to the top shelf.
