1U P4 Systems

hi Bari/Jim

i know that this is a beowulf mailing list...but ...

and yes... i'd be curious to see how many clusters are
using 1U vs 2u vs 4U...etc..etc..

For Making ones own chassis... it is NOT that straight forward...
there are always costs and *oops* that add up... that sometimes
its cheaper to buy someone elses stuff even if its not quite
exactly what is needed...
	- we tend to build customized 1U chassis per vendor
	specs...

not many people can cut and drill the holes as needed...

the $50 1U chassis are flimsy paper .... not worthy of being
called a 1u chassis...

the typical $250 1U chassis are okay...but those still twist
so if its in a tack and hold held by the front mounting ears...
those motherboards will twist...

our 1U chassis is 48 gauge steel.. it wont bend like theirs does..
and there you cannot drill it either.... its extremely difficult
for the ordinary hobbyist

and yes...one-z-two-z is fine... but thats a hobby as opposed to
building a 1U beowulf clusters ??

make that extreme pain...
