thats a link to the mobo so you can see more, i have a bigger case so i was wonder whether a Geforce 550ti would fit on the mobo. It has two slots which you can remove for the DVI and mini HDMI on the side of that case ?
A typical DVD ROM is 150mm and Mini-ITX is 170mm, so 'looking' it appears the MOBO is Mini-ITX.
Keep in mind OEM MOBO's often use custom sized MOBO's, the smartest move is to measure the exact dimensions before replacing anything -- if the goal is to have the replacement fit properly. Otherwise sure a refurbished (same) replacement.
