I just bought a Dell Poweredge 2650 off of eBay, and was going to outfit it with a USB2/Firewire PCI card so I can attach some cheap bulk storage to it for backup purposes. The Dell has PCI-X slots; backwards compatible with PCI, right? Try to find a USB PCI board that doesn't require a 5V capable PCI slot.. I haven't been able to; of course it's pretty obvious in that the USB host is supposed to supply 5V power to the peripherals.. D'oh! Oh well. You'll have to try extra hard to fry your machine with the wrong flavor card as the PC card connectors are keyed differently, and unless you try Really Hard or try to plug it in backwards, it just won't fit. louie
