In addition to being a wireless router, ASUSTeK’s WL-700gE also functions as a network storage device and an iTunes/BitTorrent client. It sports a built-in 160GB HDD, five Ethernet ports, 64/128 bit WEP, and “can be turned into a RAID configuration with another drive.” Pricing and availability have not yet been announced. Additional information here.
And it has a BitTorrent client that can rip down 7 streams automatically (and 10 FTP or web streams at the same time.) That’s with your PC off, all downloads handled by the router
