2021 5950X/3090 Kingpin Build (Thetis)
Thetis was built in mid-2021 as a next generation version of my Theia build but ended up as a dedicated flightsim PC. While Theia was about the bling factor, Thetis was built with no-compromise performance in mind. RGB was actually removed in this build by replacing the stock fans that came with the AIOs with quieter and more performant Noctua fans. For the case I selected the Phanteks Enthoo Pro 2 as a no-frills but quality option with excellent cooling. As with my NCase, the custom cables were made by Michael with MB Custom Sleeving.
