@matt someone looked at a pc case and went "hmm... You know what PCs really need to function as best as they can?? As FEW COMPONENTS AS POSSIBLE! after all, we all know that led lights and coloured cables are what makes a pc go faster! Not that silly component stuff. Let's just totally strip out these pointless mounting systems."
Then someone went "uh ... Hard drives are a thing" and they went
"Oh right, yeah, best leave those in at least then."
