The Intel SC450NX is a good and reasonably cheap 4-way Xeon system.
I have FreeBSD (-current) running on two systems, the larger has 
4 x Xeon-500MHz, 4GB DRAM, and 6 x 9GB disk - total cost ~ $20K
(from www.sagelec.com).  With only 1 disk and 256MB DRAM the price
is $9800.  Note that FreeBSD doesn't like the onboard SCSI chip,
you need to use an Adaptec SCSI card.

A 4-way system needs hefty power supplies and cooling, so as far as
I know there aren't any simple "quad processor motherboards"
(unless you go way back to the 200MHz PentiumPro and Socket8 -
but this would be slower than 2 x PentiumIII-500MHz).
