mate, here's my suggestion:
the image in the left is the front view while the rear view is at the far right.
In the front panel, i allocate LCD poster (uppermost) 2 USB's. Audio I/O, power button and an optical drive at the bottom. while I/O panel, PCI-E bracket, 70mm intake fan, and PSU access at the bottom on the rear panel.
the image in the left is the acrylic skeletal frame of your case, the image in the right shows how the main cover opens (like the LP640, haha!). the hinge is places at the top of the back panel and connects to the top cover.
your exhaust fan will be a 2 60mm fansfacing down.
i will make a follow-up post on the dimensions, material positioning and the air circulation diagram.
