For your reference, the Dell AT101W, ivory colored. There is also a black version. Has black Alps switches. Most people don't like them very much compared to other mechanical switches, but some like them a lot. One of the cheapest mechanical keyboards on the second hand market. I didn't pay much for these nib ones either. If you like the black Alps, they are great value for money.
My first guess would be the obvious one that indeed the PCB came from Korea but the keyboard assembly was done in Malaysia, where assembly workers are cheaper.
