No, the units we use have air inlets on the front and two exhaust fans out the rear. There are no holes in the top, bottom or sides. Info here:

In a rackmount environment you want front to back cooling. The air is drawn in from the "cold aisle" and exhausted out the back to the "hot aisle". Brough is probably referring to http://www.routerboard.com/img/pricelist//79_m.png . If you notice it has exhaust ports on the top of the rack. This is a bad idea in a dense environment. If you have a couple of U above where you can push that air to the back of the rack it's something, but less than ideal.

The RouterBOARD 1100s we're using have front-to-back cooling. Am I missing something?

I'm in the market for a rackmount MT device. Don't care how many ports (as long as it is two or more), just need something that can rack mount. Internal power supply preferred, as well as front to back or side to side cooling. What are these vendors thinking building rackmount devices with top to bottom cooling? I'm looking at you RB1000U/RB1100U/Titan Wireless Rackmount Case. They are about as useful as an armored tank with a rag top.
