Don't do anything. Servers aren't perishable. If nothing jumps out at you right now, so much the better: You'll have the space and bandwidth next year when you come across something you've absolutely got to have.
Obvious analogy: Look at your personal computer. You're not running around looking for downloads to fill all that free HD space are you? It will fill itself before you know it.
