Client, Workstation or Server

Hi,

I'm trying to find the correct version to chose....

We have about 20 Windows users needing to run Linux programs and workloads, they are only needing RHEL Client version. Our idea is to have one box for those users as they only need ssh or vnc access. As some of the workloads are cpu intensive we were thinking of using box with two cpu sockets. The question is if we are then forced to use RHEL Server version?

Rgds,
