I didn't want to hijack the previous thread, so though I would start another.
Here is a nice cheap trunk that matches the F6 nicely (especially the fast black ones .
It can install using the four spacers and bolts that come with the Honda luggage rack. So, just four bolts to install and remove (I removed the rack when the trunk is on).
The dimensions are about 22" wide, 11" tall and 14" deep. They are available on ebay through a handful of sellers.
