Building/Maintaining a server

[Superiodity]

Hello all.

I'm new to overclockers but know there's a lot of really intelligent people that know all there is to know about computers/networks/servers and all those things, so I thought i'd ask for advice here.

Basicly I need to know what sort of hardware/software i'd need for a business server that 2 large and 2 medium business will use, needs to be able to handle a call center, E-Mail, 4-5 domains, SQL databases and remote access.

Also needs to be secure, always backed up, easy to maintain and maybe a way to use windows 365 with it?

I know i've probably missed lots of information out so feel free to ask anything and i'll see if I can get an answer for it.
Thanks for reading and layman's terms would be appreciated

Yeah, I see your point I was basicly told to do the research for it but no idea where to start.

Would it probably be a lot better starting with a small server and building it up to the point of 2 large companies once the user is confident/experienced enough to maintain it, or would it require a lot of knowledge/high end specs from the get go if it's going to be built upto that?
