Thanks for rating my system everyone
Allthough I believe I don't deserve such high marks. There are many others that do a better job than I have.
I realise that it's hard to hide those wires with the sidepanel fans, but you could try to route them via the hinge at the back of the case. If you sleeve frontpanel connectors and all visible fan-wires, it's much nicer.
My TRUE uses two Yate Loons in push/pull configuration. What I have done is use 8 zip-ties to mount both fans without using the Thermalright wire clips. You have to pull 4 zipties through the holes on fan A, through the TRUE, and through the holes on fan B on the other side. The remaining 4 zipties are then used to fasten this configuration. Here's a picture to explain all this:

Note that the HSF is incredibly hard, if not impossible, to mount after attaching the dual fans. Especially in a case like mine. So I advice to mount the HSF prior to attaching the fans.
If its just a case of being unable to use the wireclips because of closed edges on your fans, I suggest using a small saw or knife to cut out the edges. I did that before I went for this push/pull and it's actually quite easy.
