Mac Pro Inspired Case

I really like the mac pro case inside and out. But wish it had more airflow on the top and bottom. My goal is to create a case, with mac pro quality (and a little smaller), but combine the designs of the mac pro, and the enthoo mAtx evolve. Here is what i got so far, I would like design suggestions/ideas. Still trying to figure out what to do for the front. Height wise the slanted part is half an inch tall, is that too short?

Case dimensions are 16x16x7, those were rough estimates to start, likely to change. Thickness of panels are 1/8in.

thanks for the advice

Ive decided it looks better having a grille type thing on the top front, still don't know if i like flat, or slant better. heres kind of what i mean by grille... see keyboard art
