dual motherboard is ez ??
	- stacked one on top of the other ??
	- if one fails, does both come out or just the failed one

	- there is basically no advantage of 2 mb in one 2U case
	( and you lose the redundancy of two 1Us compared to one 2U )

	- power supply should NOT die ( in my book )...
	it needs better quality ps and better cooling and 
	not exceeding the typical 50% max load on the supply

- i wonder how fast a dual p4-M is compared to dual p4-3.6G
	or compared to dual-opterons ..

mini-itx comes with dual-GigE ... in 6"x7" .. capbable of running P4-3.6G 
	( we squeeze 10 of um in per 4U .. )
