So I found some spare parts for the 4pin 4pin cable at my work. I soldered two of those things together and saved myself $10. I mounted the m2-atx into my case. sorry the pics are so fuzzy but i decided to use my phone to take the pics.
It's hard to tell but I'm using mounting brackets to hold the m2-atx in place. Gives it a little space between it and the case also.
