Ok so I received some components today I won't be able complete the board though I still need the MOSFET IRLB 8743 I have plenty of MOSFET IRFZ 44N used in the version 1.4 board. Along with this I still need the 24 pin ATX power plug.I will have to wait for those components.I will continue to assemble the board up to the point of installing the Atmega and the MOSFETs this will give me time to start with the frame.

I did some reading and apparently the 8743 MOSFET is recommended because of a lower operating temperature.
