They're pretty costly, but they run cool, take up wee space and use only 65 watts for the CS500 standard version. We've standardized on them for our colo recommendation. They charge about $2700 for a case, power supply, passive backplane, floppy drive and P120 CPU card that comes with video and all the basic ports. We always source the hard drive and memory separately due to their exorbitant rates. I never priced one out without the CPU though I was thinking I'd ask about that next time I call. They're CPU prices are the most outrageous part, and I keep reminding them that they're out of line with the industry by a mile. The price differential between the P120 and the P166 for example is $900! You can get a P200 Pro for less than that.

If you have any luck getting CPU-less pricing from them, please tell me or nanog@. These are VERY nice colo boxes. Avi
