I currently have a thermaltake overseer rx-1 full tower . and I have been thinking about upgrading to a nzxt h440 mid tower because I want to get sleeved power supply cable extensions and the nzxt h440 has a shroud over the power supply that will cover where I connect the cable extensions . I currently have x2 evga gtx 780 sc acx's in sli and a regular sized atx motherboard . will the nzxt h440 have enough room for my x2 gtx 780's to stay cool ? and will my graphic card temperature be hotter in the nzxt h440 then my thermaltake overseer rx-1 ?
