I just bought a SkullTrail and QX9775 (one CPU to start with). You can see photos of the assembly of the system on my blog: http://dvanderboom.wordpress.com/2008/08/23/bad-ass-development-rig/.
What was used for cooling for the overclocking article's machine here on Tom's Hardware? I'm surprised they didn't say! Large heat sinks and monster fans, or something more extreme?
I bought a Thermaltake BigWater 7860is water cooling unit, and the Coolermaster case I'm using has almost a dozen fan slots and plenty of ventilation, so we'll see if I can't get the 11x or higher multipliers to work without overheating. I'd love to get it stable at 5 GHz, but we'll have to see how it goes.
