Thankyou for your response...

I suppose I will look elsewhere

Dell has never sold a system with six pci slots.  I believe most systems were sold with four, maybe five in the older systems. 

 

What kind of hardware do you have, that you'll need six pci slots?  just curious.

It's a physics experiments that requires a suite of electronics running into six separate DAQ (data aquisition cards). It would be most useful if I could have all the data running into the same computer.

 

I'm actually on a Dell right now that has 5 PCI slots (it is an older model).

 

Thankyou for everyone's replies.

i'd go with what ejn63 suggested, the poweredge servers.  there are plenty old systems out there and im sure you can find expansions that go with them. 

 

Best places to find them would be ebay or a computer expo/show near you.

the same will go with dell's competition.  the only way you'll get six pci slots, if you bought an aftermarket motherboard.  In today's standard, a motherboard with six pci slots is outdated.  So it may be difficult to find a new one.
