Another option, you could get an netgear n900 router (WDR4500). It has a service called ReadyShare, free to use, that allows you to share your USB storage attached to the router over wan/LAN. Pretty easy to setup.
Thanks for your input. I actually bought the TC, but will return it as I just placed an order on 2xWD Red 2 TB drives + Synology DS212j.
