looking for Mac Pro bits

I'm on the hunt for a RAID card for use in my home mac pro 3,1. If you have one in a retired machine and can part with it, please send me a note. I have some SAS drives I want to use in my mac but they require a raid card installed.

Also passivly looking for an external e-sata card. have an array connected via firewire but its slow as molasses running up hill in winter.

thanks!
