Apple’s Mac mini server gets rid of an optical drive and gains room for two hard disks. It uses Snow Leopard Server, and has the same 2.53GHz Core 2 Duo processor as the updated 320GB Mac mini.
For $1000 it includes two 500GB hard disks, 4GB of RAM, and GeForce 9400M graphics. The 320GB Mac mini will stay at $800, but has the already mentioned new processor, and ups 2GB of memory to 4GB. The $600 entry-level Mac mini has a faster 2.26GHz processor (was 2GHz), 2GB RAM (was 1GB), and has 160GB of storage (was 120GB).
