Project: RainMaker (PC-343B w/ Horizontal Mobo and Triple Loops)

The McMaster reducer is 4860K657. I own a set myself and it's one of the best.

This is correct. My nomenclature in the pic is a bit different from McMaster... what I called a reducer, they call a bushing. The coupler's (called nipples by Mcmaster) are part # 4860K605 if anyone's interested.

@MechOz, the stock motherboard tray is held in by several rivets... Just drill into the rivet head with a drill bit that's a bit larger than the rivet core (you should be able to gauge the size of the rivet core from the non finished side) and the rivets should just drop out and the tray should be free.

I'll try to post some more pics of the finished product later tonight.
