Overclockers Online has posted a new review on the Ultra m998

In terms of build quality, the m998 excels with its brushed aluminum finish and steel reinforced structure. Ultra has really put a lot of thought into the case as seen by the removable motherboard tray which includes part of the back panel, allowing you to install your expansion cards without struggling inside a cramped case. The interior is spacious and should satisfy pretty much everyone. One of my favorite features is the ability to attach casters to the bottom; every heavy case should have these!
