I was hoping someone could shed some light on this for me. I purchased a cm stacker model number stc-to1-uw. The mobo compatability is extended atx. I just noticed there is another kind of cm stacker model number stc-to1-uwk that supports atx,e-atk,btx. My question is did I mess up and buy the wrong one? I have an asus a8n sli deluxe mobo. Will I be able to mount my mobo on the cm stacker version I bought?
