There are a few problems of installing hd5750 low profile card in 755 sff. the card has a thick heatsink.  755 sff pciex16 slot is right next to hdd cage.  It does not accommodate thick card. 1st you need to uninstall the cage.next, the card has double fan and is long.  755 sff heatsink shroud may not allow you to install a long card. third, tdp is 86w.  definitely exceeds pciex16 slot power support.  Plus the sff has a wimpy psu. fourth, the card is double slot width.  Sff pciex16 slot is for single slot width card only. You may need to cut away some chassis back metal wall to fit a double slot card. [IMAGE] [IMAGE]     [IMAGE][IMAGE]
