The Helmer is actually a cute little “case”. When I first heard of these as computer housings, I wanted to build something like that, and actually even bought a Helmer from Ikea. It ended up as cabinet for small stuff though as I was unsure how form factors would change in the future, and drilling/sawing the drawers in form promised to be a ton of work. (And I didn’t have the money for five computers at that time.)
Since the rendering is done on GPUs these days, I’m not sure how the airflow would affected, and whether the graphics cards would even fit in the drawers. Maybe someday.
