Hey, I haven't received my pc yet but I wanted to know if in the future I would be able to SLI graphics cards. So I went on the site, brought up the Define X1 and went on to configure it, added a second Graphics card and went to proceed, a window then flashed that the Motherboard was not compatible with the RAM and since these are the ones already selected for that build it has me slightly worried, can anyone shine any light on this situation?
