What servers do you use in your data center?
 

I'm looking into purchasing some new servers for my off-site data center. I'm not positive if I want to use server or go with an online data center for this work. What would you recommend I do?

It depends could you give more details ? what you gonna do with these servers ?

If you have good budget than going with data centers will be good options there you will good uptime for servers
