Blades are really only good for render farms, JBOWS (just a bunch of web
servers), SETI and the like. What are you thinking of running on this?

Is your goal purely high-density? Your backplane, what is it for? SMP

P4 min-itx with gigabit port are available. If purely for density, might
want to look at nano-itx.

Yes, it can be done. Cheaper setup is using standard ATX or even mATX.
I'd like that as you dont have to throw away your mobos, just add them
in your chassis.Then setup something like the CPU boards on the Sunfire
x800 series. A handle plate on one end, an edge connector board that can
distribute power, ethernet, kvm etc, a box with guides and a pair of
large power supplies, fans to suck the air to the back etc. I did a few
designs over the years. PXE seemed the way to go, with a master board to
control all the others (only hard disks on the master board. I
experimented a bit with 4 miniitx boards, but they were and are too
expensive and too scarse. I'd like to find very cheap mATX boards with
gigabit ether on board. That would be ideal.
The really cool thing to do would be a box with backplane and the edge
connector would connect into the last PCI slot and do an SMP box.
