I have the NZXT Vulcan and it's a great case. The Arc Mini by Fractal Designs is really nice, too. I don't know their volume but a quick look on newegg would help with that.
You will be hard-pressed to find a case with a depth of 16" or less, usually the largest dimension for a micro-ATX case.
Rosewill makes a cheap m-atx case that is 14inches deep and 14 inches tall, but it looks kinda iffy from the reviews. I'm looking at the Vulcan, but I'm worried that the handle is a bit weak. Have you found that to be the case?
I looked at the Fractal, but its almost as big as my mid-atx case.
