I'm going to start off with a big thank you to Minerva who helped build this list, planetarian for help explaining electrical stuff both in this thread and in PM, Blake for his all around knowledge, wetsuitxninja (Ben from No Limit Airsoft and Paintball) for getting me a good deal on some parts, EDI1st for his guidance in the early portions of this build and others on ASC, ASF, and ASM to help nitpick, give me my list, and help edit the list a tad. I am looking for the best possible parts on a high end budget. If you could help me out with the questions I have and give me advice on which parts to use, I would greatly appreciate it.
