These cases are great if you're not paying over $20-30. They are very attractive, IMO. Plain, black (unscrew/remove the hideous silver "Ultra" logo though).
I disagree that they're well made, though. The metal is pretty thin. You can't push too hard when snapping in your backplate, for example, or it easily bends outward. And be careful around the case or you'll get cut...too many sharp edges. Also, installing a hard drive directly into the case causes a vibration/hum. I suspended my hard drive in the CD bay using rubber bands...it's ultra quiet now.
Aside from those issues these are decent cases. For $9 shipping AR it's a great deal, for $0 it's super hot. I don't need the case so I'm going to hold out for free shipping. If they never offer it, I'll likely never buy it.
