Pros: Tried and true chipset, linux, windows, windows server compatible. Small, low wattage, QUIET, stylish. Slot under faceplate for a laptop sized cd/dvd-rom
Cons: barebone comes with no processor fan, no case fan, no cd-rom. Room for only 2 hard drives. NO CASE FAN
Rumor has it that they will offer the ICE Genie as an optional separate purchase, which is nice for the processor but I don't know if it's sufficient enough to cool the HDD's. I built one with a celeron 420 and a stock core 2 duo proc fan. (the stock proc fan that came with the celeron was DOA) The fan size on the back is 92mm, I bought an antec 92mm case fan and it's very quiet, the loudest fan on the system is the small power supply fan. It has the slot under the faceplate for a slim dvd/cd-rom. You would have to dremel mod the front clear plastic to make it look right, but it's easily doable. AT LEAST it has the option.
I built it for a Windows Home Server and it works perfect.
