I want to build another one of these in the future so I'm going to make a list here of things to do differently.
* Fix the top-heavy proportions (the new design adds 1/2" depth at the back and 1/2" height at the base and knocks 1/2" height off the marqee -- see dimension changes in the attached image)
* Put the usb connection on the right side
* Move the volume controls to the speaker panel
* Print the marquee on opaque vinyl so it isn't so bright and doesn't look washed out
* Buy and use shorter cables
* Find some good quality 2.0 speakers so there is more room inside
* Mount an exhaust fan and grill
* Cut the hole in the bottom to better dimensions for easier access
* Use a micro-atx or mini-itx power supply
* Find a way to make the headphone jack work
* Route a slot for the left and right edges of the marquee so there are no gaps
* I've updated the artwork a bit. The most notable change will be that the white bar across the front of the control panel is now black. It will make the cp look less busy.
* Find a dimmer and more evenly spread out light source
* Put the power button on the outside (maybe on the back near the exhaust fan)
