Re: Big Computing (ish)
I'm afraid I'm not too clued up on the enterprise side of this lark, I more specialise in personal use and dabble in small business networks. However, I would agree that if you're utilising the server to it's full capacity, then in the long run it's probably cheaper to have your own!
I'll leave it to somebody else to make hardware recommendations, I don't think I know enough in this area, sorry.
