Build advice

[CrashChicken]

So i have p8h61-mx motherboard and i3 3220 cpu. So what i need is a pci card with rj11 that can get adsl2+ in and another card with 4 gigabit rj45 jacks (or more). So that is a modem and a router in the same box. Can this be achieved? Should i rather use seperate modem? Do you have any recomendations or personal experience on products that i should use? (Sorry for my bad english.)
