I do not know in other regions but the Latin people like to set up the PC on benches, I even had a similar one (I sold it), this is common here, sometimes they make at home in acrylic or steel plate, wood, the image shows a example home made, the boy only paid to cut and turn the steel / iron plate.
They also make adaptations, the example GPU uses the casing of a model but inside is another board, they seek to improve the cooling anyway.
It is well crafted https://imgur.com/a/0y5yeFc
