Well it looks like im one of the many making my own case. i ready to get started but theres only one thing im stuck on. i cant decide what thickess to get. im looking at either 1/8" or 1/4". the first would be easier to work with, but im not sure about its strength. what thickness would be good for a case (the case is going to be 20x18x8). thanks in advance for suggestions.
