(meteorobs) Looking for advice choosing fireball cameras (video)

What are your scientific goals? Do you really need the resolution 
afforded by multiple cameras (a setup that will introduce many 
management and processing challenges)?

At the least, if you want meteors and stars in your data, do not use a 
color camera. All of the Sony HAD based B&W cameras have similar 
sensitivity, and all are a LOT better than any of the color camera 
choices. A color sensor reduces both sensitivity and resolution while 
adding little or no useful data. (Sense-up modes are not useful for 
meteor work.)

Well, I'm in the process of buying just such a property, so I want to find a few cameras, but I have a few questions about what equipment would be suitable.

I expect I'll have to build a dedicated PC for this purpose, so any tips on what minimum spec to go for would be helpful.
