NAS with a Bittorrent client

Does anyone know of or have any experience with a NAS device or media server with an integrated Bittorrent client? I was looking through the hardware tab and searching the internet and haven’t found any definitive answers. I did find some NAS drives on newegg that claim to have a BT client but I’ve never heard of the maker but the reviews were positive. I was looking at one of the HP devices like the MediaVault or the Home Server. Any advice or insight anyone can offer is greatly appreciated.

Thank you for your time and consideration.
