Generally speaking, necessary HW is not related to the user size but how much virtual user size you'll specify and how complex script you write.

Each agent can handle about 900 vuser if the agent have 2 core and 4GB ram.
However it's measure when the script has only a single HTTP call.

So if you need 4000 vuser (single HTTP call), you might need at least 5 machines.

Anyway... we currently have 35 agents and these machines handle 1000 developers needs here.
Each agent has 2 core and 4GB ram..  (It's not expensive machines. Some of them are even VMs.)
Just buy cheap one. and please install CentOS 6.X in these machine.
CentOS is the main OS on which we test ngrinder.
