Hello, I am part of a American Sign Language group that uses a video system to play sign language videos for the deaf. I am currently wanting to upgrade the system from a dvd setup to system that will allow me to store all the dvd's on it for easy play back during teaching sessions. I am really interested in a iMac setup. I have seen some done and wanted to get some input on a average setup that can be built for a decent price. Here is what I think I need. iMac 20" or 24" Apple Remote - For simple navigation setup for classes and such. iPod Touch - To use as a remote during class. Will a 1st generation work for this? External harddrive - To store the video off of the main system drive for moving to new systems or incase there is ever a system crash. UPS system I already have a mobile TV stand I will be securing the iMac to. The videos are not high detailed. There are images on the videos, but most of the time it is a person or persons doing sign language to explain certain lessons. My Budget s around $700.00 This can go up some if really necessary. The group has put this money together to make this possible. I appreciate any input you might have on this project.
