As was mentioned, desperatly needs wire management. The front panel looks almost exactly like a stock case I've seen on Newegg. Still cool looking though.
You need to paint the inside of the case, gloss black would be best, but any color would be better than bare metal. Sleeve your wires and route them on the frame with zipties, or some other method to keep them from hanging around too much.
Add a side panel LED fan and style grill. Maybe a meteor light bar, or some lazer led lights to spotlight the inside after you clean it up in there. Maybe some EL glowing wire to create some accents to the inside.
That case is a really good base to mod with, have some fun.
found that case, it looks like this;
The whole case is only $52, whoever charged you $100 to make that front panel.....I dunno.
In fact, I may use that case as a base for a project I am planning. Have to swap out the blue cathodes for red though, but yeah....I'm getting some ideas now.....
