I built my own 4k home golf simulator!! how much did it cost? ($3,127) E6 Connect, GSPRO.

Home built golf simulator assembled from items bought on amazon, Home Depot, etc. This was an easy build, I learned a lot. Started out as 1080p but upgraded to 4k this year. I've been an E6 connect subscriber for the past year but am now currently subscribed to GSPro.
