Extra information on Modding the +5v rail

By Atomic Eco- from link above.

Ok, here goes!
The article discusses two ways to increase the voltage on the +5 rail:

1. Modifying the PSU by connecting an adjustable 5 kilo ohm resistor in series with the R82 resistor. Note that the R82 is not removed - the 'outer' end of the R82 resistor (the one that is closer to the edge of the PCB) is disconnected from the PCB, and the black wire on the picture is connected to the free end of the R82 resistor. The red wire is connected to the now free solder point on the PCB.

Now you can adjust the level on the +5 rail, but the author warns you not to overdo it, as the voltage on the +12 rail is rising too, and can rise too high.

In the article they also connect the resistor into a copper clip, for easier adjustment (and safety I guess - it's not hanging free inside the PSU).

2. The other way to improve the +5 voltage on the motherboard is to connect additional +5 wiring to it. The author recommends connecting the extra wires using standard power connectors, but of course this can be done from inside the PSU too. You need a powerful soldering iron for melting the enermax connections inside the PSU, as they are rather sturdy.

The article does not show with pictures where the extra wires are connected on the motherboard. The author writes that they are either connected to the "thick +5 copper coil" or "the center leg of a MOSFET". You'll again need a more powerful soldering iron for connecting to the coil.

Hope this helps! As a disclaimer I would like to say that I'm not responsible for people messing with their PSUs and connecting wires and stuff to them. I haven't done this mod myself (I don't have an Enermax) but the language in the article seems clear and unambiguous enough.
