I feel like this design has some conflicting design cues. What's the purpose of the angled design of the side panel cutouts? What's it trying to convey? Speed? Motion? Where is it drawing your eyes? It seems, to me, to evoke architecture or structural supports, but ones that feel superfluous to the design.

What about the logo? The font choice and stylized wing graphic don't seem to fit with any of the other design elements. Or eachother, for that matter.

I think you have the basis for a nice minimalist design here, but I think you've taken a wrong turn by trying to add "design." It seems like so many designers feel like they need to justify their existence in a company and end up overdesigning things. Not that that applies in your case. Dieter Rams said, "good design is as little design as possible." That's worth keeping in mind. Check out more of his design philosophy and designs.

If it were me, I might change the cutouts to three equal-sized horizontal rectangles. Or replace the side panel with a single piece of perforated aluminum that wraps around the top and bottom. That might hurt airflow too much though. For the logo, I'd work on the font and either simplify and move the graphic, or ditch it altogether. I'd like to see the screws on the back-side panel/stand moved out to the corners (or hidden entirely), if possible. The shiny power button clashes with the matte/satin finish of the rest of the case. Would be nice if it were flush and the same material/finish as the rest. I'd like to see more alignment between the elements on the front panel, though I'd probably ditch the optical slot and logo depression anyway (silkscreened or lasered logo instead).
