I use the large size 65% Boveda Packs as reinforcement for the beads my coolidor and think they work great. For some reason the winter here is difficult on my cooler and adding 1-2 boveda packs helps maintain humidity. The beads alone keep it at acceptable levels (62% on average) but I like the added boost to keep things at 65%. I will also take a boveda pack out and throw it my my tupperdor and hermetic cigar jar when I have an overflow situation. Using the packs like this; they last about 6 months.

I would feel comfortable using them in the situation you describe above. The only thing to consider is that a large boveda pack is going to cost you between 3-5 dollars depending on where you purchase them and in what quantity. If you are only using boveda packs, you need new ones about every 3-4 months. You can recharge your boveda packs if you want to. There is a thread going about this. For less money you could get the appropiate amount of beads and be pretty much set. Especially in a large desktop humidor like you are describing.
