[comp.sys.mac.hardware] What is a CMS SC20a 20MD Case

victoro@crash.cts.com (Victor O'Rear) (07/05/90)

Does anyone have some knowledge of CMS's SC20a 20MD hard drive case with power
supply?  The local electronic surplus toy store (Gateway) is selling them for
a low price and I wonder what I should look for and what I would need to add a 
second hard drive to my plus.

Thanks.
