OS for home server

It isnt as simple as you might think. I have 4 cable modems that all need to be load balanced. I am using Wingate on my PC to load balance 2 modems through a proxy. But i would like to have a PC that just serves as a server and a router. I have narrowed it down to Windows server 08 and PF Sense. They both seem to be able to do what i want. I was just wondering if anyone has used either or tried to accomplish this and what your experiences were.

Google : "WINDOWS WORKSTATION 2008 V II + BONUS BOOT DVD AND EXTRA APPS MENU" that way you have a Vista like O/S that's all tweaked out .


I'm d/l to try out for later . Sounds very interesting .
