Currently my 6 PC's are just lined up next to each other and its pretty ugly, a waste of space and different box styles. I think I would like to rebuild them all into a nice looking rack mount case, possibly the following:

Has anyone done this and ran into issues. Any problems building a high end setup into these boxes with space or ventilation? Just wanna know if I'm getting myself into any issues before i drop a lot of cash on this.
