I need a 1U server case - halp

[saedrin]

Hi guys, I'm hoping this is the correct section. I need a 1U server case for my pfsense machine, and I'd ideally want to keep it fairly inexpensive. I'm using a simple Atom based mini ITX motherboard with a single intel full-height network card. I need something that can accommodate a standard PCI riser card to fit the network card, but small enough that ideally it isn't 24-36" deep and built for an extended atx application. I'd also be very keen on finding something with an included PSU so I don't have to hunt down a server PSU somewhere.

Any suggestions or ideas?
