Why is the power supply at the bottom? Wouldn't that cause heat to move up through the caee as well making everything unnecessarily hot?
What sort of PCs are you using? It’s totally normal for the PSU to be at the bottom: that’s what the fans are for.
Don't listen to these niggerfaggots. If you aren't rack mounting your gaming PC in a server cabinet along with all your mining rigs, you are doing it wrong.
Rack mount = the PSU goes on the side of your machine.
I haven't built one in over 10 years and have been using high end laptops for work. When I last built one, all power sources were mounted at the top. What changed to have it move down to the bottom?
They got heavier.
So you need a stronger case.
Too much weight at the top of the PC.
This way they keep the case the same.
PSUs have been primarily bottom mounted since ~2008. You still see cheap bottom of the barrel prebuilts with top mounted PSUs these days, but it's uncommon. What changed is higher TDPs of modern CPUs and GPUs; the top is more or less reserved for more ventilation/fans/radiators.
They started mounting power supplies in that fashion to keep it cooler. Most cases have a port in the bottom, (usually with a dust filter) for the PSU to pull cool air through, exhausting it out the back. Though I remember cases when they first started doing it, that would mount the PSU fan side up instead, and pull air from inside the case.
