As I said every PSU is different so I can't tell what yours is like internally. If it's the same as mine then the sinks would be live so I'd not favour epoxying a water-block to something that's live. If it made electrical contact then the cooling system would become live either shorting to earth or through some other part of the PC.

Unfortunately I don't have the time or equipment to make them for others atm, also as said PSU's all differ in design and layout so unless I had access to every PSU I wouldn't be able to ensure a successful build. There can be a lot more to it all than just simply cooling the mosfets effectively, I built mine because I wanted a fanless environment, willing to accept killing it or other parts of my PC. Others have done it have a look on
http://www.digital-explosion.co.uk for instance make it sound easy, but I'm not so sure myself and wouldn't suggest you try unless you are fully prepared to accept the risks of failure in some shape or form.
