If you're in doubt about the legality of something after reading the manual, the best solution is to go to Q&A for clarification. Even better, print and bring the Q&A with you to the arena. (Inspectors have access to the printed Q&A thus far, but that's a lot to page through when you're looking for one exact question.) Failing that, be prepared to adapt if the inspector calls you on it.
That said, I don't see any gross problems with the linked parts
except for the fan. Why? The fan has a motor not permitted for use on an FRC robot. The GDC
explicitly blocked hard drives under similar logic. On the up side, there are fans in the kit you could use for most any purpose.
