Looking for a Huge PC Case That Can Fit 4× RTX 5090 GPUs (Using PCIe Risers)

Hey everyone!

I'm looking for recommendations for a large PC case that can accommodate 4× RTX 5090 GPUs.

The main issue is that my motherboard's PCIe slots are too close together to install all four GPUs directly, so I'm using PCIe riser cables to connect them.

Right now, I have everything running in an open-frame setup, but I'd really like to move the entire system into a single enclosed case.

A few things to consider:

• 4× RTX 5090 GPUs, connected via PCIe riser cables.
• The GPUs don't necessarily need to have their display outputs accessible from outside the case. Ideally, only one would need external access, while the other three could be mounted entirely inside.
• I'm looking for a very large case with enough room for flexible GPU placement and good airflow.
• I've been considering something similar in size to the Thermaltake Core W200, but I don't need support for two separate systems. I just want one massive case for a single PC.

I'm open to unconventional solutions or creative GPU mounting options, as long as everything fits inside one enclosure.

Does anyone know of a case that could work for this setup? I'd really appreciate any recommendations or examples of similar builds!

Thanks in advance!
