SIX tuners is only THREE PVR500's, only THREE PCI slots, and only THREE 
cable feeds from a splitter/amp.
Both tuners are on the same board on a 500.

A six slot motherboard should give you the capability of having 3 HD 
cards and 3 PVR500 cards for a total of 6 tuners.

I would worry at that point, that the machine might become IO bound if 
you tried to record from all six at once...Although I have recorded 3 
shows at once with an HD3000 and PVR500 combination on a VIA SP13000 
motherboard.
