Just for fun i suppose.

Well i had a look a one and all the soldering seems to be hand done, and the components don't look anything special, so do you think you could buy a kit or the individual components and build a PSU for real?

I am sure you could get a circuit board printed out somewhere for a few $, but obviously you would need a circuit design of which there is bound to be one on the net somewhere.... maybe end up blowing your self up in the end?
 
It could be done, but without being specifically tooled up for manufacturing PSUs, I don't see what advantage there would be other than amusement.

First of all, you'd need a sample PSU to reverse engineer unless you already know how they're built. That would require a couple of days just to discharge the thing so that you don't kill yourself opening it up. Also, I don't imagine the components are cheap. Have you seen the size of those caps?

I'm sure it can be done, but the process would be far more exensive than just buying a PSU. And the result would probably be of pretty poor quality also. Personally, I'd love to do something like that just as a personal project to work on. But it would be expensive. And you'd have to REALLY know what you're doing.

I've actually got a degree in Physics(not that i learned that much in it though!) . We did a module in electronics in it and built an ultrasonic rangefinder from scratch, was a couple of years ago now but i have an idea of what it would be involved although no expert.

Like after each component was soldered in we would test the waveform with an oscilloscope at certain points on the board to see if the waveform matched what it should, quite good fun making it and i just fancied another project in my spare time.... I dunno, i will look in the net for any info.
 
Then it sounds like you might well know what you're doing. And it could be a pretty fun project to work on. Just don't expect the result to be better than something Corsair or Seagate can sell you at half the price. :D
