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.
When I stopped caring about super quiet: E5 1680v2 @ 4.5Ghz, 980ti, i750 SSD - JS9500 & Dell P2715Q for dual 4k@60 because reasons
