In defense of the review, a lot of the cables seen in that "rats nest" are unroutable behind the motherboard tray. The back fan for instance, there is no way to route that behind anything. You could route a 4-pin molex behind the motherboard tray I suppose but you would still have to take that fan cable somewhere towards the front. I can see how the ability to snake the power cables behind the tray would be useful but sometimes, dependent on the power supply, the cables just aren't long enough. Another instance would be the SATA and IDE cables. In my opinion, those are just as ugly as the power cables and far more difficult to hide.
I understand where you are coming from, the mention of this feature would have been nice and can actually be added into the review, but to deem the build a rats nest because a feature of the case that only a handful of cables could have used, wasn't mentioned or applied, is jumping the gun a bit.
