I mean, it is 2010.Bakplanes make direct front to back cooling hard. non-modular platforms can do it just fine however.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.
The server vendors also somehow manage to make an empty case that costs less than $10,000 (they'll even fill it up with useful stuff for less than that).
Unit volume is little higher, and the margins kind of suck. There's a reason why hp would rather sell you a blade server chassis than 16 1us. Equating servers and routers is like equating bouncy castle prices with renting an oil platform.
