I just bought that bottom, a middle and top for $130 thinking I got a deal. We agreed on the price and he delivered, it looked great. all my shop neighbors were digging the nice "new to me" box, everything was fine. then I got it inside and filled a drawer with wrenches, box felt wobbly. added some sockets and ratchets to another drawer and the thing felt like it was going to collapse. I got instant buyers remorse and will be re-selling it asap.
is it nice looking, yes.
does it hold tools, yes.
does it scare you when you open a drawer with more than 3lbs in it, yes.
it may work fine for a computer tech or someone with tiny screwdrivers and small pliers but when you lay out a single layer of any sockets/wrenches/ratchets/etc to fill the drawer, that drawer feels like it will break off when you open it. I didn't even get to put tools in the bottom cabinet drawers, I started at the top and quit after only a few drawers. made me sick really.
