Wide server cases

where on earth can i find cases like a dell poweredge 6400, yeong yang cubes (dont even know how much those are...) or something like this to mod for my own case build? maybe i should just buy material and make my own. i have been having a hard time finding this stuff, but it is late...i know there use to be a site that had oem cases...anyone have it?

also:

Google "server chassis"

Intel
Supermicro
Lian-Li
Silverstone
Cooler Master


MRFS

a bit too steep. for the price of the cases, i can get a poweredge 6400 server used on ebay...but thanks for the help. maybe i will just scrounge around for sff case (like the nzxt rogue) but extend the height of it to match a standard atx height, or full tower. i want a massive cube style thing, without spending tons of money. i guess pop rivets and a metal bender are in order then. just have to buy full tower side panels, and figure out how to attatch them...
