Summary: If I had to do it again buy the 8gb ram sticks for up to 32gb for Server 2008R2 standard it is cheaper. Wish I had enough for a second one this year. Maybe later. Loaded OS and Exchange 2010 in less than 2 hours thanks to the dual CPUs.
Pros: I own a computer company and bought this is warehouse our exchange 2010 and SQL files as well as FMSO roles. Rnning 24 gb ram with 5 300gb drives SFF. This server does not disappoint you will be sad if you passed this up.
Cons: Bought at HP for $3450. New Egg is lower priced. Bought 360G7 later in the same month here at the Egg. There are no other issues with this server.
