CPU Cooler: C7 Cu is a great cooler, but with the default fans runs super loud. If you can, try to change the fans to a Noctua 92mm fan for quietness while maintaining the same performance.
GPU: Idk if your GPU could perform well in Sentry, it might thermal throttle, but if you want to try do try it. I'm curious to see if it's possible and
someone put in a 2080 Ti with it, though his ambient temps were so low. But if you want to play it safe though, I would limit it to a 5700/2060 Super, or at the max 5700XT/2070 super (not recommended by Zaber but I've seen some guys do it).
Check page 35 and 36 for Zaber's recommendations
Case: Try not to use magnetic filters, as it will definitely impede cooling by strangling airflow. I know others have tried with success using magnetic filters, and if you want to try it out please report back, I'm also curious if it could work.
Other than that, I think your build is pretty solid. CPU itself is great, MOBO, RAM, PSU, and Storage is also great.
