HCs come with pipes sticking out of them, usually either 5/8" and/or 3/4" diameter. If you want you can sweat out the pipes (undo the solder with a blow torch) and re-solder in some barbs. However, this isn't necessary as I just recently found out. Apparently you can take the ends of your tubing and boil it in water for 30 seconds or a minute, and then stretch them with some kind of taper, then just force them over the pipes, let them cool, and clamp them down (being careful not to crush the pipe.

You got to pull out the old fittings and put new ones in, or at least cut any bends out of the old ones. See an exellent guide here: http://www.xtremesystems.org/forums/showthread.php?threadid=25182&highlight=bonneville ...........See the pics of the core I modded in todays post 
I gotta get pictures up of what Ive done with mine. basically I cut off the tubes about 1" from the core then, I sweat a 1/2" copper pipe to 3/4" npt fitting to the tubes. then used 3/4" npt to 1/2" hose barb fittings. (lowes didnt have 1/2" pipe to 1/2" npt so I had to get the 3/4" anyways. The reasoning for doing this is that the plumber solder has a lower melting point compared to the solder holding used to assemble the hc. sure my barbs stick out about an extra inch but I dont care its all going in an external box anyways.

You dont use a soldering iron. You have to use a torch, that heats up the solder thats used with the brass.

popular because of its size, not its effectiveness. The Chevette core is probably the worst of the HCs out there. Not that it's bad - it's still WAY better than any black ice or simillar. Basically, once you have the smarts to decide on going the HC route, the rules of thumb are 1. bigger is better, and 2. single-pass, low restriction is better than double pass high restriction.
The Fedco 2-342 (GDI 399090) HC is among the best, and under $30. there's a test somehwere on proforums, but I can't find it at the moment.

MY BAD I listed the CHevette
The one he is talking about is 9 1/2 inches for height, the rest is the same. SORRY
EDIT: You can put 2 120mm fans on one side of that core

I have the Chevette core but I have not gotten everything hooked up so I cant give you any temps. Have you read through the stickies? I picked up alot on water cooling by just reading through them.

Its a good core, if it was so bad then not that many people would be using it. Its better than BIX from everything I have read, here and other forums.
