I have a mac mini running leopard server that is gong to be replacing an ubuntu server machine that sits in my closet. the ubuntu machine is great because i can configure avahi to broadcast itself as an xserve and it shows up in finder as a server. i have no idea how to change the broadcasted system type in osx though. sure it's a little gimmicky, but i suppose i just enjoy seeing the little xserve icon in my sidebar. i know that the icons are located in /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ and i could just rename the xserve icon to the macmini icon, but then every mac mini on my network would show up as an xserve. i know this seems pointless, but it's just one of those things that i want to know how it works.
