1U P4 Systems - holes

[alvin at Mail.Linux-Consulting.com]

hi Robert

the $50 1U case off the shelf...
	- you have to drill all holes for motehrboard, powersupply etc
	and the metal it uses is like paper... ( extremely thin

the average off the shelf 1U case is about $250...
	- one fd, one hd, one cdrom...--or--
	- 2 5.25" bays w/ floppy

our chassis is a range... 2 drives up to 8 drives...

All 1U chassis suffer from:
	- room only one pci card
	- atx connectors on the back of the motherboard has to be
	  the Intel CA810EAL/D815EAL style...
		- NOT the dual NIC supermicro motherboards 
		- except if you buy the 1U from supermicro themself

For a list of all the 1U vendors...
