When I put my MCE core (dedicated) in, I'm going to need it to replace my current fileserver (running Linux). The routing / DNS / DHCP etc are obviously there, but I'm going to need to add additional back-end services like e-mail (probably PostFix) and antiVirus (ClamAV). Squid and Dans Guardian are needed to keep the kids safe (and their parents sane) on the 'net. I also want to use the box to store family documents, should I try to integrate with the MCE users and directory structure, or have a parallel directory / user set for the PC's? I assume Apache is installed for the web admin and I know mySQL is there, so the other bases are more or less covered.
