Cheers man. I have built a few PCs before, I was more looking for specific help on rack mounted PCs. It's like having a server rack unit, but it runs as a PC instead of a server. They are good for studios because you can just have it all mounted on one unit with all the other rack mounted stuff you have. You can get a keyboard on rails as well, its all just neater than having a desk unit. Also leaves more room for monitors (both kinds) and a mixing desk.
