Expected Server configuration for 100 users

I can second the fact FreeBSD + nginx is a rocking combo. We've been
running that for years under ever increasing traffic and it only requires a
few basic adjustments to the OS, even fewer in 10 since a lot of system
defaults were cranked up for modern times. Our current hardware handling
nginx related duties are sporting Intel L5520 procs and have been in
service since 2009, only now in the process of being replaced due to aging.
If systems had a guaranteed infinite life these boxes would still be good
for quite some time. If you go the Linux path it's probably a similar
situation, nginx is likely not going to be the part of your stack which
