How do.
I need help with selecting a server.

Ive got 12 clients of my own and the company I work for has over 20.
Each of these clients sites are hosted on separate hosting packages.

I'm getting to a point where maintaining the sites is becoming a serious pain so I want to get my own server for hosting any future clients.

The director of the company I work for is happy to invest in me getting my own server. I've been offered up-to £2500.

So two questions really -

1. Any suggestions on what to get?
2. How much of a learning curve am I facing to administer the darn thing?
