20 employees - this is fairly small, but not too simple depending on your daily usage. What are your users doing with the computers? Are you running and special software? Are there developers?
I agree with above as you should do better homework at identifying what the users do & need.
For example: whether your users should use laptop or desk computers - it mostly depends on costs and mobility needs, are your users working while traveling or are they only at the office?
Whether your server should be inhouse or external depends on costs vs. security needs as well as do flexibility and required access to the actual hardware.
Hardware also depends on cost vs. do you need something dedicated to graphic processing? heavy financial or statistical work?..
As for Media solution:
"We also need an internal media server (we have thousands of big image and video files, and the archive grows bigger every year)" -
For that there is a great open source solution called Kaltura - http://www.kaltura.org.
Kaltura will allow you to syndicate, manage, transcode, integrate with other solutions, etc. at no costs and easily.
Version 3 also runs on the Amazon EC2 in case you decide to go cloud based, or you can just download the software and install on your Linux box inhouse.
