I have a working G07 CBO 19 inch chassis for sale. It is working, but has some horizontal curl that needs to be tweaked. It has just been capped with a Bob Roberts kit and mod as well as a new HWC.
Tip to help your sale: I had a CBO chassis rebuilt and had a TON of trouble adjusting the pots on them. I was able to fix them real easy though. I got some TV tuner spray from radioshack and blasted the crap out of them. Worked perfect after that.
