Perforated PVC and zip ties. Makes it very easy to swap out components (and faster to put together the board in the first place). Well, I say it makes it easy, but the final board hasn't been built yet. However, the temporary testing board is made from pegboard, which is similar; actually, the pegboard is probably harder to work with than the PVC since it has fewer holes per inch.

We've done plywood, polycarbonate (Lexan), and acrylic (Plexiglas) electrical boards before... acrylic loves to shatter, plywood is kind of heavy (we don't use the really thin plywood, which I imagine is significantly lighter), and polycarbonate can get kind of expensive. Acrylic and polycarb require you to drill holes (<- a big issue with thin acrylic) and mess with those tiny nuts; plywood can just use wood screws (although we usually use bolts for that too).
