I have a small case for this machine and am trying to add a small (low profile?) GPU to it, to support 2x 4k monitors. I say small because there's not much space left, and I'm keen to keep the temperatures down - so passive cooling is ideal. I'm also a little nervous about quite how much power is left from the 750W PSU.
This is NOT a gaming rig - it's just for desktop use for development - so the only real requirement is that it can support 2x 4k monitors with very low framerates.
Appreciate any ideas!
