I recently built desktop using i7 core processor and a Corsair SSD and am amazed how fast it is. Now would like to try building a server to replace our old one. The old one uses a Xeon X3210 and 8GB ram and a RAID 5. I would like to scale up in speed and also in the ability to handle outside web page hits where the max user or max hit to the web page is 25 simultaneous different users (not open to public). What would be a good board, processor and setup and I would like to do it with SSD's, where possible, to help the speed in SQL and asp.net tasks.
I am a biz owner with a little understanding, so keep that in mind as you answer. I do have a remote IT guy that helps, but I like to decide this stuff with input from EE folks.
I plan to use SBS 2008 and will plan to run Exchange and SQL and would appreciate input on how to use old server in the mix with the new server.
