I got a mini-ITX server set up (although it's a desktop board haha.) Here are the specs:
CASE: Silverstone Mini-Fortress Black:
SilverStone Technology Co., Ltd.- FT03-MINI
CPU: Intel Core i5-3470S @ factory default settings
Motherboard: Intel DQ77KB
RAM: 8 GB SODIMM DDR3 @ 1333 MHz
Power Supply: It's actually powered by a laptop power supply, however the Silverstone allows you to install a SFX power supply.
OS: Windows Home Server 2013
It has no DVD drive, it only fits a slim DVD drive but I just use an .ISO of my Windows Home Server DVD to my USB and installed it from there.
