A little hard to get to, but, their amazing!

Glad to see this thread continues. We decided on the tall SEKTION cabinets (without doors) from Ikea kitchen dept. These are about 8 feet tall. We have 8 of them side by side and they're amazingly strong - no bending shelves. I highly recommend this option!

Over time the shelves will bow and possibly pull away from the sides.
This is very cheap construction most probably MDF or worse plain particle board. As a short term solution maybe.

The best way to do this is cabinet grade plywood with a chin of hardwood on he shelves 2 inches wide. This braces the front of the shelf and plywood is stiffer than MDF. Doing it this way would cost at least 4 times as much. The shelves should be the long pieces and The divider the short ones. This prevents the load from damaging the cabinets. Records are heavy and the load is fluid which is why shelves will bow under records.
