1500 clients is quite a lot, but not hard to handle from a single 
machine if you select a cpu capable of doing ssl quickly. eg a power6 
machine with a few cores would handle that without any problems.

If you want to stick with commodity hardware, a couple of quad core 
amd's should also fit right in.
