Why would you blow it up with a SMPS? I built a PSU for mine with a 5V switch-mode wall wart that originally powered a USB hub and it works fine. There's a 100uf filter cap on the 5V rail inside the machine already that will smooth things out. The real danger is letting the 5V rail get too much over voltage; that's what happens with the original power supplies, and it will cook the RAM chips in a hurry.
