MATX & PS for 6900 XT

Considering my first MATX build but am having a hard time finding a case and power supply that will fit and power my 6900XT (267mm). I've found a few cases that seem to fit until more research tells me it will fit as long as I don't install a front fan. Also, cant find any MATX power supplies above 585W.

Suggestions for case and power supply to run my 6900xt?

Add'l info if it's helpful: I have the nvme SSD and fans. I need to select a Mobo and processor. I'm not into overclocking.
