you should put some holes in that mobo tray so you can route all of the PSU cables behind it; most newer cases have that incorporated into the design. having a PCI card that needs a 4-pin molex on the mobo is such a pain in the ass, molex cables are the roughest to tuck. you're lucky you have a modular PSU though, easier to hack the cables down to size and not have to find room for a bunch of connectors you aren't even using.
is that one of those newfangled gamer network cards i see there?
i didn't have to "hack" the cables, my psu came with all sorts of lengths and types, i have on hidden under the psu, and a bunch on the right side panel.
here's my monitor set up just cause i'm so happy with rotating my secondary monitor
