I used to have an Aerocool M40 (media version of the small QX2000). I was very impressed with it, especially bang for buck. I used it as a lanbox before I got an SG-07 however, I found the construction and useful bits like tie down points and vents very useful. The only downside I found was that the paintjob wasn't the best, I managed to scrape a nice chunk out of it one day which is when I changed its use to a media PC.
The design/layout was fantastic, if anything more useful than a BitFenix Prodigy or SG-07. It just became to big to lug around to lan parties though (being a dual level micro-atx-motherboard on bottom layer, HDD/ODD/PSU on top).
The white Xpredator X3 certainly looks the business but it would be nice if the side window sat flush with the rest of the side panel. The window construction/design looks a little dated.
