Server Hardware Recommendations

[Gollimari]

Hello all,

I am doing some research towards the feasability of starting up a server system for a small consulting firm. I have done lots of research into different systems such as citrix etc but have pretty much narrowed it down to Windows Small Business server 2008 Premium Edition.

My question now is what would be the hardware reccomendations for a system running the above OS. There are ~10 employees that would mostly all be connecting remotely (they work on site).

Features desired:
-central email database
-central files
-access to Primavera databases

A pretty basic setup. Anyways, I'm trying to put together a list of reccomendations as far as processor speed, RAM, storage.

I was thinking something like 2.4GHz quad core, at least 2GB of ram (preferably 4), and 500-1000GB storage.

What do you think?
