After doing a little bit of searching to me it looks like an old Seasonic case, I was going off of your power supply. As it turns out they made cases as well. Were you looking to upgrade your case or need info on it?
That case could be made by Rosewill or Thermaltake since I don't recall seeing anything from Fractal or Coolermaster that resembled that front fascia. Also, there should be a barcode or part number on the underside of the case, might want to parse that as well.
