I have just bought a shuttle PC (sexyyyy)with the onboard n-force chipset, athlon 2400, 80GB hard disk and 512MB DDR 2100 RAM (2700 ram has a problems with heat! - use corsair ram) and the pulsar II card fits perfectly in the provided PCI slot. This baby has been running for a few day with no problems at all - although I have yet to push it to the limits, I also have a P4 shuttle based on the intel chipset which I'm planning to break -er-test to the limits...
Any one else have a shuttle? - please - no jokes about cars and spacecraft....

Regards
