I am building a couple of side-by-side cabinets for the shop. They will be 30" wide. The space between the top and bottom inside will measure 34". Should I make all the drawers the same thickness ( about 5 1/2") or would I utilize staggered drawers more, say 4 drawers at 3" depth etc? Recommendations are welcomed on this storage solution. I will be making something separate for my Festool systainer slide outs so not putting much with height in the drawers.
