The very easy way to tell the difference between the 4 types of tower models is to specifically look near the power button area on the front and the LED/buttons in the front. Pay attention to it carefully.

All tower models come with a 386 CPU. 



Generation 1\\
MODEL 1, MODEL 2, S1, S1 \\  \\
Parts are not as interchangeable.  Requires a SCSI card in order to use hard drives which are external only.  Power Supply card different than other 3 generation tower models. CPU has a socket so it can be upgraded.
