I'm looking for a case that excels at showing off GPUs. The design would be similar to the Phanteks Evolv Shift, but larger. I would want a chamber/side specifically for housing SLI GPUs mounted vertically, with a TG side panel to show them (and nothing else) off. I'm surprisingly having difficulty finding a case like this and I'm not sure why. It must exist. Any help would be appreciated. Thanks.

I'm thinking he means something more like this.

 
They made a YouTube video for it. 

That defcon is exactly what I mean! Thanks for the tip. I'll look it up.

I don't think I've ever seen anything like this in a production model. It doesn't seem to be a high demand request. So, going this route will likely be a custom case or modding an appropriate case for this arrangement. I would imagine it would be easier these days because many new cases do have the one vertical mount GPU spot, you would have to figure out how to get that second one above.
