Looking for advice - Which bitcoin mining machine is best for my conditions? Data center (Rack mount)

I am an employee at a very large data center, it has come to my attention that I am allowed 6 units of rack space in a shared colo supplied with 110/20a 220v/30a power, and a 5mb internet link free of charge

If I wanted to invest up to $2500 into a rack mounted machine, without power usage being a concern, which would you suggest?

I would like the best TH/S per $, energy consumption is not a concern
