Sandeep, I was thinking about asking you for a yearly update on your server recommendations, cause mine cost me $10k 2 years ago. The fixed fee for the installation and data migration was more than your hardware costs 1 year ago.
My servers require assembly. The hardware also comes from 10 different brands. Each one, the best at what they do. There is often a large markup on the higher end. The only thing that really changed is that there are newer IvyBridge processors E3-1230V2 and LGA 2011 is released for those who need a more robust platform. I'll probably start posting that on my blog (need to make one first). E.g. my desktop (more of a server at this point) would cost me over 14,000 from Apple or Dell. It cost me much less than that. ~3K
Upside is you can use your local IT guy if something goes wrong. They can usually do same day. Usually ends up costing 2-3K less than Dell or Lenovo. So you should have extra funds left over. I have received some requests for servers, but I'm only selling them locally until I can get a cost effective and fast backup solution. With Server 2012, this seems like a possibility. Possibly even full failover (2 servers) for less than 7K for those larger practices.
