Bigbruin.com has posted an article on the Ultra Products Aluminus ATX Case
Another great feature of the Aluminus is the removable motherboard tray. Two thumb screws on the right side of the tray hold it in place. Remove the screws and slide the tray toward front of case and it pops right out for easy installation of the motherboard. Mounting the motherboard was a joy... the stand offs were already in place and in this case even mounted in the correct spots.Ultra Products Aluminus ATX Case Review
