I just can't conceptualize an OS X Server inside a Mini. It's an underpowered little trooper as it is, needs some serious hardware help before it should be allowed out on the big streets.
So I'm thinking this particular rumor is a red herring.
OTOH, if they could indeed cram in the hardware, an additional Ethernet port, a (much) better CPU, then Wow. It would be cool, to say the least.
For most things like file server, LDAP (for small company), web server, application server (small company), email server, etc...... You do not need a lot of horse power.
There are weaker linux based servers out there working fine day to date. The extra Ethernet I need, CPU IM ok as is, extra memory user replasable would be grand. Small disk is fine for booting and OS.
I need something small like that to take with me when I give security training so I can setup different hackable web sites for the studends to practice on and other network devices to atack during the class.
