Using the CloudOS from Neverware. I successfully installed it on a computer and imaged it successfully. I think you would classify it as Chromium OS but it has been modified with more driver support and other things. I am using the free version not the paid for one with Google Apps support.
I used the Linux with multiple partitions single disk.
I was actually able to install this on several different hardware models with no issues as long as the hard drive was the same size or larger than my original test machine.
Optiplex 360.380, and 390
Lenovo X130
Inspiron Duo
Might be able to extend some of the old hardware this way.
