So its been a while. I am much closer to finished and have a lot of pics to post tonight. Couple things to note: Just got a "new case" in yesterday. I am going to move my Asus Xonar STX from my desktop to my carPC. Just ordered a Fusion Brain and sensors, so hopefully will have that soonish. My goal is to fit everything 100% inside the case, including the M4-atx. I will be using "terminal strips" to connect all wires neatly to the back.
The FB will be based out of the 3.5 HDD bay and the power supply will be emptied for the M4.
Also, for those anti 64-bit, UEFI is only compatible with 64bit Windows Vista and 7. I should have researched this more, but slightly disappointed i cant get my cold boot time faster than 16.5 seconds (6.5 for windows 7 and 10 for bios). Installed UEFI/Win7 64 and with some minor tweaking hit 18 seconds. If I took the extra time I put into the initial install, I think I could have broken that. But, back to 32 bit we go.
