Project is Done. I decided to mount the monitor to the pegboard after all. (it was an extra monitor lying around anyway)

All and all the project went pretty smoothly with the exception of getting a defective board.

phpvirutalbox is put together really nicely and it defiantly saves me space on my other machines having them in one single location makes things much easier.

Untangle took me 2 installs to get squared away but it is working very well. I hope they keep up with the support. Boot up and shut down on the machine does take quite some time though.. I did decided to let Untangle handle the DHCP and DNS as well and seems to be doing a good job at it.
