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.
