Do you not have much space pee-air? You seem to be throwing everything away. I've got all my Macs tucked away around the apartment. One whole closet is dedicated to Macs, and I have 7 LC 5xx Macs under my bed. It all fits nicely.

I've done cap replacement on my Performa 400. However it was my very first Mac so I guess it has some sentimental value. It's running great now but it doesn't get used much.
