I've built probably 10 computers at this point and I went with this after having issues with my NR200. Tons of space for a full size 4080 and theoretically a 4090 as well. Not a ton in terms of cable management but makes up for it with the great airflow, storage options, and the USB C port on the case. Everything is running nice and cool.
