What is "dual-channel DDR"?

[Andrew Hammond]

If you've got a server room to put it in (these puppies are LOUD), you 
can probably get an A8440 chassis w/ motherboard for cheap these days. 
Celestica has stopped producing them in favour of their new design, but 
it's still a decent system.

Populate it with a pair of 846 or even 844 processors, inexpensive 
memory and say 4 x 146G 10kRPM disks. You should be able to do it for 
under $3k, including taxes. Leaves you room to add CPUs and memory. 
Unlike Xeon based multiprocessor boxes, you can mix and match CPU 
speeds. Memory too, as long as you're consistent in each bank.

You really should talk to the guys at Alliance Tech.
