Not very familiar with the two chassis. What are the pros/cons of the Dell T5500 vs HP Z600?

The Z600/Z800 have both CPUs mounted on the motherboard and each CPU uses the same type of CPU cooler, which is proprietary. Another heatsink may fit but the fan has a special plug and I'm not sure whether it will boot if it's not plugged in.

The T5500 has 1 CPU mounted on the motherboard and comes with a crummy aluminum heatsink. The one I linked to works much better. The 2nd CPU and RAM bank must be mounted on a special riser. The CPU cooling on the riser CPU has something to be desired. They seem to be selling a little cheaper than the Z600s though.
