Although many people employ them and find them useful I am not a fan of drawers just below the bench top. Being versed in woodworking I'm sure you would avoid the obvious problem of press mounting interfering with drawer opening but over time you will be spilling powder on your bench... every once in a while you'll even knock over a full canister of powder. It happens.
Powder will end up migrating into the drawers, even when they're closed and given enough time you'll end up with a considerable amount in each drawer. To clean them out, (a vacuum with a crevice tool is the easiest way), you'll have to remove everything from the drawer to clean it and clean off each individual item. Not a huge deal but it's time taken away from the ladies. Overall not a good situation.
It's pretty much human nature that when a newb plans out a bench they do it with certain pieces of equipment in mind. That usually doesn't work out all that well since loading equipment is like money, you always want more and more. Will the incorporation of drawers limit what equipment you can mount directly over them or render them totally inoperable?
We can't forget the most important safety consideration... at some point your cigar ash is going to fall into one of those open drawers cluttered with powder and the closest thing at hand to extinguish the fire is going to be your glass of scotch. I don't think 18 year old spirits is a UL approved way of putting out open flames.
As you become more and more involved in loading you may find that you start using different electric operated devices; digital scales, case feeders, bullet feeders, Dremel tools, casting furnaces, etc. The bench top can quickly become cluttered with electrical cords.
Over my two or three month loading career I've taken a lesson from computer table designers. Simply cut two or three holes in the bench top, one at each end and one in the middle toward the back. Attach power strips to the two front legs, run your power cords through the holes and plug into the power strips. The bench stays uncluttered, (I'm very, very big on an uncluttered loading room), and you have the advantage of killing all the power by clicking the power switch on each power strip.
They also make a handy place to plug in your vacuum, flat panel and sound system. See, ya gotta plan ahead.
Have fun... you've done a beautiful job on the bench.
