Need PC rack enclosure recommendations

[James Weisbin <jweisbin@mindspring.com>]

I'm looking for an ATX style PC-enclosure suitable for mounting in a 
standard equipment rack (horizontally, server style). The only ones I 
have found are more than 21" deep, which sticks out the back of a 
standard 20" deep rack. Height doesn't matter, but aluminum would be 
preferable because it is lighter and easier to transport. If anyone has 
any recommendations for a good unit I would appreciate it.
