Can someone please give me the part number for the starter box that comes with the hyper 7 pbs rtr.

Part No.
HS101

Do you know where you can purchase that starter box?

HS100 if your in the US. But you really want the HS101 if you can get it. Try www.nitrohouse.com

If you're looking at getting a starter box, why not spring for the chrome top? It is also available at Nitrohouse (but currently out of stock I see). A much, much, much better box in my opinion.
