^ if just a file server and other services that linux/bsd can do then sure pick your fav distro and run with it!
Just the other day I was looking to setup printing on my ipad I got for xmas, uses that stupid bonjour to find the printers. Well I had disabled most of the multicast on my windows box because just not having any need for it. And it was sending a bunch of noise that my gateway firewall was logging so just disabled it.
So since I have a linux VM running on my esxi host 24/7/365 anyway, just installed cups on it - connected it to the printer and there you go ipad can now see the printer being shared by cups
Took all of 10 minutes to setup vs having to turn mulicast back on my windows machine that would of generated a bunch of noise that isn't needed to be seen on my network.
linux can be a great solution for a bunch of stuff! Enjoy!
