Like others mentioned, it doesn’t seem far off stock. The things I can pick out that are mods are:

• bl touch (or something like it). This is an automatic bed leveling tool. So instead of spinning the little cogs under the bed all the time to get the bed level, it will probe the bed before printing to build a map of the bed position, and print accordingly.
• general parts upgrade. This is a simple upgrade kit that’s just an increase in quality. Better springs, stuff like that
• mainboard upgrade. Might just be upgraded to a silent board. Might be upgraded to something more… hard to tell.

I don’t see much else that stands out as being particularly modded. Hope that helps.

Clearly, the statue was carried by ocean currents south from New York, through the Panama canal, then back north where it washed ashore at the tip of the Baja peninsula in Cabo San Lucas, Mexico.
