please see below for mods that I could find for the Iron Man. I collected this data as I want to set up a IM Fan web page with info of mods you can purchase and DIY mods. I was fortunate to have 80% of these mods when I bought this machine.

Hope the info helps.

The following sites are places known for various non-standard parts that can be purchased from along with costs as a quick guide. And if you discover more places please send me a message and I can add them to the list or make changes if availability changes.
