I bought two nice book shelves at the local furniture store.  I looked
far and wide for many months to find a bookshelf that was deep enough
for piano roll boxes, and they are exactly right.  They are beautiful
wood, with glass doors.  The wood trim on the doors and the unique
finish make them look like gorgeous old furniture.

There were only four shelves, so I then bought 1/4" glass for
additional shelves and drilled holes for those little push-in shelf
supports.  Each cabinet now has 16 shelves, and each cabinet holds
a total of 256 regular size rolls.  It was a bit pricey, but I couldn't
be more pleased with how they look, and the fact that they hold so many
rolls.
