I am looking to make a cheap server for mainly test / practice reasons for my programming and file sharing / downloads and whatever else i can think of to turn this server into, mainly low importance stuff.
3TB of storage plus an SSD for boot/main files, an i7 for hyperthreading, 32 GB of RAM. and a ridiculous deal on the case and CPU (that's going to be my case suggestion for everything as long as that deal lasts. Antec Sonata and 500 W PSU for $10? YES Please!
the 2500K is sandy bridge, 4 cores, 4 threads. the Xeon E-1230 is 4 cores, 8 threads, also sandy bridge. the 3770 is 4 cores, 8 threads, and ivy bridge -- lower power usage and a little better all around than sandy bridge.
