I hope this one will work out for you ! I used to pick up external drives from our Value Village store. I picked up a HD20 and a HD40 @$7.99 each. I bought a TopDrive for the same price. I swapped in a 350mb drive into that one and it sits under my Mac Plus with O.S.7.0.1* on it. It really depends on where you are, when it comes picking up old Mac stuff. The external drives are a nice way to go and they lift the monitor up a bit and can resolve some heat issues.
