FWIW for anyone looking for same stuff OP did, I sometimes see system pull Radeon 6450s on ebay for $20~30 shipped that are low profile with a full length fanless heatsink.
(most others either have those tiny screamer fans that love to die to dust, or are like that XFX board and use a heatsink that violates the low profile size)
They always have 1 hdmi and 1 full size displayport, and for some reason the heatsink is red. Only some have the half bracket though.
They work well, although I grab them as a nice cheap way to add displayport to older corporate boxes.
Nearly dead silent HTPC ver 2.0: i3-4340 w/ Noctua NH-L9i on Z87E-itx inside CM130 elite, fanless PSU, SSD OS drive

microcenter & ebay = severe risks to my wallet
