What should I get him for his Birthday?

My boyfriend is reeeally into Dubstep, and DJing, and he really enjoys the show 'Dexter', however, he's already watched all the seasons. :( He already has a DJ set too, so I can't really go above and beyond there. I was just thinking of buying him his favorite cupcake, or mini cake, and having them write 'happy birthday' on it, and giving him a funny card. I am going to surprise him at his house before he wakes up, and sneak in his room. But is that too little? Help me.
