Are there any elements that are important to you? Like appearance, durability, cost, ease of construction, joinery, finish??? As I mentioned in yesterday's thread, I used melamine. The Sysport I built lives in my home workshop, and seldom gets moved around. I chose melamine because it is reasonably priced, easy to buy and transport, decent looking, pre-finished on both sides, finished front edge, pre-cut to 16" depth, durable enough for my situation.
ps - It's a carcass or carcase.
