Gotta big new Green Box, but where should I stick it?

Ten years after getting my first Zilla (John Wayland's old Godzilla 1800, S/N 003), and then a Z1k, I've finally graduated to a Z2k for the Karmann Eclectric!  

Mounting this 2000 amp monster poses a quandary.  Do we saddle it directly to the 9" motor case?  My first controller endured some fairly violent clutch chatter before I got that all sorted out, and it died mysteriously while the car was tied down in a trailer, but with the telltale smell of popped capacitors.  Otmar had warned that extra vibration is something to avoid.   So- I seek consensus.  Is the eye candy of a color-matched controller riding atop its motor-mate with very short input cables worthwhile, or should the controller sit a foot away mounted vertically on the firewall, possibly even on rubber isolators for maximum vibration dampening?  In the past decade, many other motors have been ridden by their controllers- any regrets out there?  The other option is to mount it to the firewall, where there's plenty of space and probably enough structure to support that 24 lb chunk of copper.
