My computer came in yesterday so I got mostly everything installed and setup. I was really anxious to install it but I soon realized that it was 3am so that was a no go, lol.
As for today, I began to tackle the power supply situation. What I decided to do was take the AC-DC adapter that came with the dell and use that case to hold my M2-ATX PS. The adapter casing ended up being the exact size of the M2-ATX. I simply cut the wires from the original unit (Power cable from wall and power to PC). I then went ahead a soldered all of the wires together for the battery and ignition and then just plugged the stripped wires into the MOLEX connection and crimped and taped those together.
It was now time to test it out see if it worked. I hooked it up to my battery, plugged in the battery and to my amazement, I didn't mess anything up HAHA.
So I came back inside and wired the LCD into the other MOLEX connector and tested again. SUCCESS! The carputer was now up and running for the first time in my car!
As of right now, the computer is under my passenger seat with all of the wires already ran. My LCD is just sitting in my ash tray under my radio until I pull that out and mold it into the dash. Also all of the wires shown will be hidden then.
Here are a couple pictures of how it looks right now.
