This is my desktop. I currently have four computers (and four keyboards and mice, two sets of 7.1 surround sound speakers, two screens, plus the laptop) on the desk, one in the Xaser V to the far left, with a portable HD on top and thermometer.
There is also an EEE pc (the little laptop with the fish in it), my main rig in the Xaser VI (better than normal thermaltake). On the other panel is a large 220mm fan blowing cold air from a cooler part of the room.
In the main rig, there is an ARTiGO Pico ITX PC, which acts as my always on server, complete with 120GB HD and 1GB RAM with a whole 1GHZ of processing power.
The main rig referenced in my sig, is badly cable managed due to the size of the case meaning that the cables won't go under the mobo tray and connect to the GPUs without some serious work. Fully air cooled with a total of fifteen fans, very quiet except when its playing games.
Also a picture of the hygrometer (measures temperature and humidity) which records onto paper strips. (It was bought in the early 90s when a server room was being decomissioned)
I think I need a bigger desk.
