While you could probably build a linux router that is just as fast as a
real hardware router, you're always going to run into the moving pieces
part of the equation.
In almost all scenarios, moving parts are more prone to failure than
non-moving parts.
It's quite possible to build Linux-based devices with few or no moving
parts. Small embedded boards, and flash drives, are common and cheap;
and for low-load situations it's possible to build a passively-cooled
(i.e. no fans, so zero moving parts) system.
Higher-performance setups with a few moving parts (mainly fans) are
still possible, but at some point you have to balance the time and
effort of R&D and performance-tuning your system. If you save a few
thousand dollars on hardware, but spend a few days tweaking everything,
you may not come out ahead after all.
At least two vendors (Imagestream and Mikrotik) offer complete packages
based on Linux; the latter also sells the software separately, for
installation on your own hardware, and both offer support if you need it.
