Before I make some unwise decisions, what are your ideas?

So someone gave me this old g5 Mac Power PC (No I ain't an Apple fanboy) and I found out that it was super scuffed up. So, since I can't stand the look of it ight now I took a picture of a different one of the web and did a bit of PS on it to get a Portal kinda theme going on. I do know that I can go a bit over board with PS and I regret some of my decisions in the past when doing so. Anyway let's cut to the chase. Does it look decent at all? What I'm trying to do is make it look like a system that may be used for file recovery for Glados (And before you say that it wouldn't make sense, remember that Cave Johnson literally drank jillyjuice that came from the moon! So yeah that happened.) or whatever.

The bottom right doesn't apply to my casemod. It was in the photo I ripped off of a google search since mine would give photoshop a seizure if it saw it.
