Welcome to the forum, wvoider.
You'll only know what you're going to get when you receive it. There's no guarantee what's inside. Even the name on the front panel could be different or blank.
Regarding the flying resistors, those are power resistors and they can get warm to hot. By mounting them above the board, it aids heat dissipation and prevents scorching the PCB.
Oh, and with regard to the color of wires, they're not guaranteed to correspond with anything in particular, either. Trace them out to see where they go and, hence, what they're for.
