Build or Purchase: Rack System?

[Mike41793]

I would suggest building out of plywood finished of course, it will stand the test of time against humidity. Or if you use melamine I would paint it to help it with humidity.

I will likely end up building a rack, I have the tools and the know how to build something on the cheap.

And not only save a few bucks but make something a little more aesthetically pleasing to the eye.

Theres no need to paint the melamine. The coating on it prevents humidity from warping it. Eventually your rack may start to bow in the middle if its too wide without support.
Also ive read somewhere melamine is fire retardent. Like it cannot catch on fire by itself. Im not positive on that though...
