Sam, Yes, I ordered tiny 5 volt fans from Amazon, and I carefully laid them out and drilled holes for them with a drill press to make sure that they were straight .I glued a little piece of screening over the holes, and mounted one blowing in and one blowing out. I added a 1/8 inch nylon spacer that I picked up from Ace Hardware, and all the other screws and nuts I also got at Ace Hardware. If you are not using the 160 LPF, you will not need the spacer as it will fit. As far as the GPS goes, I mounted a little 12 volt to 5 volt (which is adjustable to any voltage under what you feed it with) converter. I use this to power the GPS and The Ultimate 3S.
Are use the 12 V power supply coming in to feed the 5 watt amplifier. If you want me to look up the part number from Amazon for the fans and the little converter, I can do that for you.
