I sent an email to the Mall of America asking where to line up and when do the doors open, and here is the response:
On Friday, August 8 the doors on the West Side of the mall will be open at 7am. People will not be allowed to begin standing in line until this time. If you arrive before 7am Mall of America Security will ask you to leave the property and return at 7am. The Best Buy is located on level 3 on the West Side of the Mall.

Friday, August 8
New Kids On The Block — five now fully-grown men who forever defined what the modern boy band would look and sound like — are back together for the very first time in nearly a decade and a half! "The Right Stuff" really is — at long last — returning to your block.
Help Best Buy continue their Grand Opening Celebration with a special performance and autograph signing by New Kids on the Block. Reserve a place in the autograph line by pre-ordering the New Kids on the Block CD at Best Buy Mall of America. Pre-order "The Block" for $9.99, starting at 10 a.m., Friday, August 8.
