Yeah, I’m not sure what would make a case obsolete other than not physically fitting your hardware. I’m using a janky mid-2000s Antec case to hold my i7-9700k / RTX 2070 build with no problems (although I fully expect to need a bigger case for any future GPU upgrades).
My hot take is that this is practically irrelevant for the vast majority of desktop users, even hobbyists. Unless you have an absolute rats’ nest of cables inside the case or you are overclocking the chip close to its thermal limits, your chip should run just fine with a small form factor heatsink/fan, which an older, non-enthusiast case should have no problem fitting. As one data point, I’m cooling my CPU with a Noctua NH-D15 inside my Antec Three Hundred. A somewhat tight fit? Maybe, but certainly no performance issues.
Is this case still worth using in 2023? (lemmy.ml)
For those unfamiliar, this is the NVIDIA edition CM-830 Stacker from Cooler Master.
