MDF, not sure what that is but I have used a cabinet from Lowes for my QT that looks like it should be used for a basic kitchen or storage cabinet

I'm pretty sure what I have is what your referring to. I purchased it white but painted black to match my DT. I was considering getting another one to use for my son's Innovative Marine Nuvo 16 that I'm going to be setting up.
I've got a workbench top I made from MDF and just applied three liberal coats of sanding sealer on it and I've spilled plenty of crap on it with no ill effects. A good coat of paint will certainly help as well.
Not to mention, those cabinets are cheap, so it's not like you're out a pocket full of money if you do have to replace it.
