Whoever came up with the demented trend of transparent PC cases is a criminal to cable management.
I bought myself a new prebuilt PC (to save on GPU cost) a while back with one of those cases and changing anything is a mild inconvenience. All the cables are routed around back to the side that isn't glass and then zip tied together into one, impossible to follow mass.
In contrast, the last PC I owned (also a prebuilt, that time out of laziness) had a nice, non-glass case and all the wires were neatly followable. When you're not constrained to hiding all the wires around back to make the insides look "presentable" from the glass side you can actually group things together in a meaningful way.
I'd redo all the wiring but I simply am too lazy. Someone remind me 2000 days from now.
