I still cant convince myself to keep the case on the desk. It has to be away from me on the floor and the desk space is only for multiple monitors, KB, Mouse, USB hub and personal items like phones remotes etc. Keeps the noise further down too when gaming.
Apple ][ and most other micros included the keyboard into the chassis, so there was little choice. My last Apple also had a "gravity locked" lid, because you were constantly rummaging at its innards. I even kept a soldering iron on my desk in those days...
Having a separate keyboard and thus a choice was one of the "firsts" the IBM-PC brought to the mass market.
Then most screens were 12-14" and rather miserable to the eyes, so in a way you needed the desktop chassis to put them close enough to see. Cool stuff took advantage of the angled CRT tube to have monitors face you like a laptop screen, but I guess that only worked with monochrome.
Micros and PC started noiseless, even if the PC had a fan in the power supply. They only part that moved was the floppy disks and who would want to bend down every time they changed one? Some software would require complete stacks of them once noise arrived in the form of constantly spinning Winchester drives or hard disks.
It was then when I relegated my IBM PC-AT into a floor standing position, because it had it look really
cool, like a Micro-
VAX.
It also ran Unix, so for the first time ever, my PCs created an illusion of autonomy, because they made clicky (voice coil!) hard disk seeking noises on their own, not just as a consequence of user action, which was how one defined "reactivity" before.
My first CPU
fan came attached to a Pentium-83 Overdrive, with Intel promising life-long replacements in case it ever failed. I'd just love to ask them today!
To this day I'm constantly maddened by the fact that the only front facing ports on my workstations top out at 5GBit/s, while accessing the 10/20/40Gbit/s stuff is popping what remains of
my disks.
But between my keyboard and the the ceiling, today everything is screen, so behind or below is the only place compute can go.
And thanks to nifty Noctuas and tinnitus the only high pitched noise is fabricated inside my head, even at 750 Watts of gaming.
It's much harder to escape the heat they are producing, quite ok during the last winters, but it puts me off my game during summer: no airco in this 1830's home.
