Glad it's not just me. Superficially they look like a great solution (IR receiver, integrated fan, nice arrangement with all IO on the back etc.)
However I lost countless hours to HDMI connectivity issues - all ended up being caused by poor quality HDMI extenders in the cases...
I have 1 of 4 working with LE and 1 that i use for a headless Motioninstall, 2 will probably go in the bin.
