I just built a spool holder for my bowden set up.. I have angled the motor mount so that your extruder with the bowden tube on both sides dips down to grab the filament right off the spool .. take a look!http://www.thingiverse.com/thing:561092
and by the way your mounting holes are available on the top. so your extruder mounts perfectly. as soon as I get a new motor and gear I will mount this up and start using it!
