With us you also get disaster recovery, software updates, & paid support and in my experience that really makes the boss sit up and take notice. The one friction point I always had when trying to "sell" an idea internally was they needed someone to blame if/when things went south. I started KangarooBox to get FOSS out into the world and to let people know that you don't have to pay overinflated prices for crappy software.
If you can set up Redmine on your server and your boss doesn't mind paying you to do it, great! I will be the first one in line to congratulate you and push you forward. If not, then we can help.

The issue here is the 4 up votes that put this on the front page instead of letting it float to the bottom of the 'New' section.
Based on those stats (wait, only one ethernet port?), you would probably be better off with something like a Soekris board (http://www.soekris.com/, esp. a 4801 http://www.soekris.com/net4801.htm). They run OpenBSD quite well...
