The barb connectors in pic 1 are very good especially for adapting to different sizes of tubing They are also ideal for high pressure systems because the piping can be secured with 10mm jubilee clips around them for added security. ( in other words like some members might have found that with too much pressure the tube will dislodge and shoot off into the air but as AC cooling systems do not use high pressure pumps there would be no need for the jubilee clips.
Picture 2 and 3 are really adapters for connecting other water cooling kits to an AC kit. Both are very good and do the job in hand all though not to fond of the compression fittings (pic 2).
Because they are big and bulky and a bit tricky to fit but at the same time they also do the job in hand. Its all down to personal choice.
Picture 4 These connectors are truly plug and cool all you need to do is push the tubing firmly into the connector and the jobs done its water tight and locked solid. All you do to release is push the black ring from around the connector inwards and release the tube out.
I personally would reccomend these as they come in 2 different screw sizes 1/8 inch & 1/4 inch. The 1/8 inch to plug and cool connector are used for the CPU , GPU , chipset block and Aqua-tube. The 1/4 inch to plug and cool connectors are used to connect up the radiators. The plug and cool connectors are very adaptable as they come in angled , T shape , and elbow version so you really can not go wrong not matter how you wish to lay out your system. These are the easiest to fit and believe me if you try to pull out the tubing from the connector your more likely to pull a muscle than rip it out.

Go for the Plug and cool connectors picture 4.

I've told this story in german several times, but never in english before...

When I once moved i borrowed a car from a friend of mine. I lay my PC on the backseat. At that time, my radiator was mountet external (-ly ??) on top of the PC.



The PC was in no way secured or anything and the radiator pointed towards the drivers seat. I was driving about 70km/h when suddenly a fire engine crossed my way.
I had to do an all-out braking (correct ??) and the PC crashed into my back.
I was absolutely shocked and asap i stopped to check if any Harm had been done to my PC. the only thing that had happend was that the window didn't resist the hit, i had to glue it back in

don't worry about the P'n'C - connectors, they hold a LOT...

says a lot for german engineering!

Aren't Legris French?

All these type fittings have their uses. The smart retailer and user keeps most of them around because you never know when you might need one.

Depending on the setup you could go with either 1/8 BSPP or 1/4 BSPP push-fits. I personally like the pneumatic compression fittings (Pic 2) as they are pretty much worry free connections. Oh and no they do not have quick disconects (Q-D) on them. You are thinking of Q-D air fittings. It is interesting to note that a 1/4 BSPP 8/6mm push-fit has a much larger hole going through it than the same 1/8 BSPP 8/6mm fittings.

BTW, Hobbes_dmS nice looking case! I especially like the cool plumbing. ;D
