Hmm... six bucks here:

$19 for two, including shipping.
Pros:
Improved air flow
Neat (in both senses of the word)
Secret super coolness factor
Cons:
Money better spent on other things
Coolness factor a super secret
Air flow is more important that super secret coolness. I'll probably just fold the IDE I already have with a bit of electrical tape.
