There are no legal pawn moves
The rooks are useless without open files.
The dark square bishop could move to d8 but that's easily defended.
The only option is to sac the light square bishop for two pawns but that could take some maneuvering.
It's pretty much drawn.
This is really not difficult. Brian gave you one example, but you could imagine many more.
It is quite obvious that in order to achieve the "box" as given, white needs to capture 10 black pieces.
Out of the 16 black pieces, all but the black king can help in achieving the box by letting themselves being captured.
The black a and h pawns don't seem at ...
Here is one simple solution:
1.c4 d5 2.cxd5 e6 3.dxe6 f6 4.g4 g6 5.g5 Ne7 6.gxf6 Nd5 7.e4 Nc3 8.bxc3 Qd4 9.cxd4 b5 10.d5 b4 11.a3 c6 12.axb4 c5 13.bxc5 Bd6 14.cxd6 g5 15.h3 g4 16.hxg4 Rg8 17.f3 Rg5 18.f4 Rf5 19.gxf5 Na6 20.d4
More moves can be added to reach the exact position with no other pieces other than kings.
