2 Boxing AoC with Hardware!!

Guys i have been a SW boxer on wow for about a year now and loved it, BUT now that AoC is here its time to move on. Since its seems that AoC will be alot harder to SW Box i am wanting to try 2 Boxing with Hardware. I already have the 2 computers as well as monitors, now all i need is alittle help picking hardware and making connections.

So to all you HW Boxers - If you where going to build a new set up for AoC that u could easily expand from 2boxes to 6 what would it be :?:

Thanks for the help... :thumbsup:
