I have now two snow leopard server mac minis, one is the older model 2.53ghz and the other is the newest 2.66ghz. aluminum mac mini. The older one is out of warranty but I want to use it as a server and I'm sure I will have questions about set up from Apple. Can I install the software for the new mac mini aluminum server on the older Mac Mini and use that license? How does this work if your server is out of warranty? I am using the aluminum mac mini without it's server software; I installed regular aluminum mac mini software on it from my 2.4ghz mac mini.
