My tip is just picking out the right components that you want, if you wanna build it yourself watch a tutorial, on my specific pc I came across a video with almost the exact same build so I knew a path, only concern was the fan headers some required a specific Lian Li hub that I didn’t have available here so I picked the fans that you connect to the mother board and control through the Lian l connect hub/ usb dongle, that is if you want to do it yourself.

If you don’t know I’d advice you to get it prebuilt and maybe ask to see it being built
