This summer we got some new dells. Most were small form factor ones with 2.8 GHz P4. We did get one that will be for video editing with 3.2 GHz, 2 GB of RAM and 4x250 GB SATA HD. When I opened it up I found what is the most ridiculous heat sink I have ever seen in a retail setup. I just had to snap a pic and post it. It is a little fuzzy since I haven't figured out macro focusing on my little camera.
The smaller computers just have jet blowers to keep them cool. Luckily they are variable. When a machine is first turned on it is loud but as the BIOS kicks in it slows it down until the CPU heats up. Haven't stressed them enough yet to get them going. Have to think of some neat distributed computing tool to try on them, 14 2.8 GHz machines should be able to chew through some good stuff.

L'Ombra needs to put on his glasses..i though I was looking at Chicago from a helicopter.
