I need to build 2 small touchscreen computers for my stepdads automotive shop. He is going to install an automated parts ordering/pricing system and needs these two terminals for his (older and non technical) staff. For specs I only really need skt 478/939, 512mb ram, integrated video, 40gb hard drive. I just do not have much experience working in the small form factor, low power area of computers. If you guys could help me look up some parts that would be great. I'm looking for $400-$600 per computer, plus monitors. I already have winxp for them. Keep in mind these will be installed in a dusty dirty auto shop, so dust filters will be a necessity. For the touchscreens, I do not know a single thing about how they interface etc, but im guessing usb. Help here would be great too.
