Here's the latest prototype of my Raspberry Pi Tower: http://imgur.com/a/Pp9aC

Working on this project for a couple weeks now. The idea is to make a very compact and awesome looking tower using a raspberry pi (Initially wanted it no taller than 9" and no deeper than 7"). That ramp in the bottom/back of the case is to make the air flow across the bottom of the pi better, keeping the chip on the bottom ice cold. And I still need to add in the exhaust in the back of the case. Once I get the physical PSU and my male/female cables I can figure out how I want to situate everything and then figured out how I want to do the exhaust ventilation.
Current Specs: 205mm Tall (8 1/2in) 170mm Deep (6 3/4in) 66mm Wide (2 3/8in)
Hardware: 4 USB ports on the front of the tower (4 wired controllers for gaming)
PicoPSU power supply to power the pi, HDD, and fan 80mm fan (Massive amounts of air flow. It's big, waiting for a 60 and 40mm fan to see how loud they are. I want air flow + quiet)
Bracket + mounting point for a 2.5" HDD (Fun fact, 2.5" HDDs are not 2.5", they're 2 and 3/4")
Extending ethernet and HDMI to the back of the case (using a male to female, they're in shipping)
Ideas: Extending 3.5mm jack to the pack of the case with the HDMI and ethernet
Another USB hub (2 ports) to the back of the case for extra USBs)
Custom power button on the front of the case
Still need to figure out how to add the power button. Thinking of going custom but I don't know how well I could do it (I've never done anything really electrical except replacing a wall outlet or fixing some wires.) Also need to make all the circuitry to go with it. And there will be heatsinks! A nice big one for the cpu, 22x22x10 (still in shipping but it should fit without touching anything else). The heatsinks are complete overkill, especially with that much air flow, but It's like $1 for the 22x22x22 + a 14x14x7 for the chip on the bottom.
All and all it's coming out well. This is the first time I've ever used 3d design software. Using Sketchup it was extremely easy to make all the shapes and it's gotten easier.
