Sell or scrap this computer equipment?

I have a nettest CMA 4000 which I acquired a while ago, and I originally thought it would be good to sell.

I have the original case, manual, installation floppy discs, calibration certificate and many many accessories (another case full), however today I find myself out of things to take apart, and I’m sure this has plenty of goodies aside from being able to see what makes it tick, but if I was able to sell it, it would be a pretty penny.

I am torn between these two options, do you think I have a chance of selling it, or should I set her down, grab my screwdriver, and see what’s inside?

Here are some pictures
