Spotted it on 4chan g/.
One guy said it was done by a user here on deskthority.
It looked exactly like the kind of keyboard i would use as my daily driver.
Are mods like this difficult?, general thoughts/links to the topic is highly appreciated.
I am more curious about the ANSI left shift and enter mod, I am one of those people that actually doesn't mind the lack of wrist rest on the 5251 too much.
