There are servers and storage arrays that have a front that is nothing but hot-swap hard drive bays (plugged into backplanes), and they've been doing front-to-back cooling since day one. Maybe the router vendors need to buy a Dell, open the case, and take a look.
The backplane for a sata disk array is 8 wires per drive plus a common power bus.
Server vendors managed cooling just fine for years with 80 pin SCA connectors. Hard drives are also harder to cool, as they are a solid block, filling the space, unlike a card of chips.
It's the same 80 wires on every single drive in the string.
There are fewer conductors embedded in 12 drive sca backplane as there are in a 12 drive sata backplane, in both cases they are generally two layer pcbs. Compared to what 10+ layer pcbs that are a approaching 1/4" thick on the router.
Aw come on, that's no reason you can't just drill it full of holes. I mean, it is 2010. It should be wireless by now. ~Seth
