Yes, the mac pro on the left I use for working from home...also tons of video editing for my personal motorcycle go pro stuff.
The mac mini in the middle runs my home theater library for my home theater room/apple tv2 in the next room.
There is a pc on the right is a gaming pc I usually let my family/friends use for local gaming...the far right pc with the 40" LED TV is my main PC I use for gaming/everything else. I love the monitor setup, it's not as close as it looks...spoiled me for gaming. Playing on my old 27" mac monitor is crap now.
I have too many computers
there is another iMac and 3 more mac mini's elsewhere in my house.
