Too bad you have to sell it now that you have added all the extras to it. The case is nice and white, but it appears that the previous owner, or yourself has replaced the keyboard from a different (more yellowed) A1200.
I am also thinking of selling my A1200 some time in the future, but had hoped that the FPGA Arcade Replay daughter board would be completed and selling before now, as that was my motivation for selling my A1200 w/Blizzard 060 accelerator & SCSI & IndivisionAGA & Subway, etc.
It is a maxed out A1200, except for not having a PPC, but IMHO, anyone wanting to run PPC Amiga software is better off getting a MorphOS3.7 or AmigaOS4.1.6 system anyway.
Good luck with your sale of your A1200, and I hope you don't regret it when it is gone (like many Amiga users are, after they sell their Amiga gear).
