Invision IPS: Best server architecture?

[microphone head]

I'm setting up a forum using IPSboard and will be using a dedicated server. Just wonder if any of you have any recommendations on the best architecture / setup for the server.

Needs to be able to cope with about ~30k users (of which probably only about ~5k will be active at any given time).

Thanks in advance chaps - appreciate.

Nothing to extreme but I recommend,
SSD
Litespeed httpd & MariaDB and don't get a control panel being it's only for one site.
