I love the brain concept as well. I especially like how none of the brains look like they come from cg artists as I don't see any that are fried, so hopefully I'll get to use what's left of mine a little while longer. I think the overall render looks awesome but I think it would probably look better in a less clean environment. As it is though, the only thing I see that might could use some adjusting is the front white cable coming out of the front left device, the one with the large display screen. In the image, it looks like its going right through the side surface of the device. On my screen, it doesn't look like it's going through a hole or being connected to a port of some kind.

Nice work!
