funny you mention this
a prefab cabinet got me back into reefing!
we had our basement refinished and tore down prefac cabinets. they were sitting on the floor waiting to be garbage when i light bulb went on above my head
i had a spare 10g tank and it would have fit perfectly on the cabinet
almost 2 years later its still holding up. i upgraded to a 15g tall (which is the same legnth of a 10g) and it never budged
i should have kept them all and lined them up. i bet i could have gotten a 125g on those babies
they are very strong!
ooo and the little shelves are perfect for foods and stuffed animals!
