That R5 2600X is actually going in my home PC and I'm taking my R5 1600X out and putting it in this build.
I went with solid state only. While the PC won't be running at all while the truck is in motion, I still think it's wiser to have solid state in such a mobile setup.
My main concern is the GPU. I chose this case because the GPU is completely removed from the mobo. But I'm still not sure whether this is a good setup for a GPU that will frequently be subjected to bumpy roads. Indiana has the worst potholes in the country and I drive through that shit hole of a state more than twice a week on average.
I can rig up something to secure the case to the cabinet fixtures in the truck, but I'm not sure what orientation to use, or if I need to do something extra inside the case to secure the GPU.
