The cube case

hope I am posting in the correct place. Currently I am building a custom case from scratch that will be in the shape of a cube(More on why it's a cube later) I however have a question though. The wire hookups are going to be inside the too section of the case. I was planning on putting a circular hole either in the front the top or the rear of the case. Which sounds best? The top is going great to be the lid and have a 120x240 radiator in the middle of the lid

Rear would be best for cable exits

Yes, rear is the best plan for PSU runs because it's out of your way and you don't have to look at the ugly modular/non-modular PSU Cables
