About to order office boxes - HELP!

I just put this box together, and to say the least, it came out cheaper then I had originally planned. Space isn't of any essence, but definitely a plus. as far as apps are concerned, it'll mostly used for quick books, ie, etc (nothing load intensive, but the boxes are left up for weeks at a time). i'd appreciate any input as the boxes are for a personal friend, and looking to get 2-3 years out of em.

thanks in advance guys!
