Yes this is the first rig to use the Swiftechs. 

The link has some resistance when adjusting the width of the link but not much. 

I found it easiest to install it this way.
1) Unscrew the "collar" (gives you more room to get wrench on the connector).
2) Attach connector to the waterblock (side closest to the collar) *
3) Tighten w/ wrench according to spec.
4) Shorten the link as far as possible
4) Insert all cards into the rig (each is connected on only one side)
5) Attach other side of link **
6) Tighten w/ wrench according to spec

* My water blocks (Danger Den 5970) have a plastic top so I attached the links to that side of each card first (outside of rig)
** This is actually the hardest part.  Kinda hard to get it started (small space, resistance from extending the link and getting threads started).

So far I am really impressed with these links.   They are very very similar to the Koolance links ($15 ea) but are fitted to allow tightening with standard wrenches.  I honestly can't believe they are only $8.
