Watercooling componant selection help requested

I e-mailed Swiftech this afternoon and got a response back 4 hours later from Gabe, talk about customer service!

Unfortunately, the hole spacing on the Apogee XT is 21.2mm. This means that the bitspower 5/8" OD fittings won't work as according to Penguins, they have an OD of 21.92mm.

I need to track down ODs for Feser and Enzotech fittings to see if they might fit.

Edit: Unfortunately, Enzotech fittings weigh in at 22mm, and while I can't find a solid number for their 5/8" OD fittings, Feser's 1/2" OD fittings have a diameter of 20mm, so I really doubt 5/8" fittings would fit.

I'm thinking about using thin-walled tubing to and from the CPU block and thickwalled everywhere else for kink resistance.

While I ordinarily don't crosspost much, I need some feedback on the condition of the two MCR radiators I received from NCIX today, a MCR220 with a paint chip (likely in shipping I suspect) and some fin discolouration, and a MCR420 with fin discolouration and a bit of discolouration under the shroud at one end.

(Copied from my build log thread, http://www.xtremesystems.org/forums/...0&postcount=21)

The bad news, the baggie for the MCR220's screws comitted suicide and let the screws escape into the box, I'm not sure if that's the cause or not, but there is a big chip in the finish on one of the end tanks of the 220.



The questions is, is this normal?



By this, I'm refering to the rust coloured areas visible on the fins of both the MCR220 and 420s, and on the end wall of the MCR420. I'm kind of concerned since I don't recall seeing any pics showing similar discolouration before, and I don't want to make a potentially expensive mistake by not taking action if I need to. (The flash makes it look slightly worse than it really is.)

Regarding the paint chip on the 220, I could touch it up myself, but I doubt it would be a perfect touchup, and it would probably bug me, when combined with the discolouration, I'm wondering if I need to think about an RMA.

Can anyone offer some insight?

Thank you in advance.
