Turn the tower on its side so the motherboard is parallel with the ground and the weight of the GPU keeps it in the PCI-e slot. It is my understanding that GPUs are able to still properly dissipate their heat in this configuration. Great article!

I have a horizontal PC chassis. Easy access to everything and has two large 140MM fans in front. It runs cool and nearly silent. I am never going back to a tower for my main PC again.

How about we move to external only GPUs with huge connectors? If GPUs are half the size, power consumption and price of a PC now, they might as well be a separate device. As a bonus the rest of the motherboard & PCs actually get much smaller. A PC without any spinning disks could conceivably just be the size of a NUC by default, something you can travel with when you don't need the beefy GPU.

You can easily buy a NUC ECE (size of a graphics card) and use a pcie cable to connect to an actual card. This is my plan for my next machine.

I predict the GPU will need to be externalized in the future with its own cooling and power system. You'll plug into the motherboard via some cable interconnect.

They're simply getting too big, power hungry and hot to keep in colocated in the case.

That is what I started doing. I build my desktop pc's in 4u server chassis[1] I had it vertical in a tower config until a couple months ago when I thought about the dynamics of the situation a bit and moved it to the flat orientation, as you would find it in an actual rack.

1. the cases(even the cheap ones) are better built and have better airflow than most tower cases, as a bonus, no rgb or windows.

> A 4080 series card will demand a whopping 450 W, No, that was just a rumour that was floating around. The 4080 16GB model is 340W TGP, the 12 GB is 285W TGP out of the box. The 3080 (10 GB) was 320W TGP, as a comparison point.

Perhaps a typo? The 4090 official TDP is 450W.

Could be. But the pre-launch rumours also claimed the 4080 was a 450 W product, and the 4090 is so niche (basically it’s the old Titan line) that it’s not worth handwringing about because it’s not targeted at normal consumers (for “I’d buy a > $1000 GPU for gaming” values of “normal”).
