To you with multiple computers, all in one room, I have a question. What do you use them all for? I mean besides servers or firewalls. I see people with 5-6 computers all next to each other and wonder how you could have a serious need for so many systems. For me, I have a main computer I use for pretty much everything. Then downstairs I have a good 3-4 computers I open up, switch parts with, and just make decent Linux rigs or servers out of them.
