Upgrades; 1) GPU. Went from the EVGA GTX 1080 FTW to the EVGA GTX 1080Ti FTW3 to the Nvidia Titan Xp Star Wars Collector's Edition (Jedi Order).
2) Cable management revamped. Replaced cables from CableMod with custom EnSourced cables with wire wraps. Much easier to handle and looks a helluva lot better.
3) PSU Shroud. Added a gloss black PSU shroud with rubber grommets for the Corsair 780T (bought from V1Tech).
4) Peripherals. Bought a Blue Yeti Blackout, HyperX Cloud Revolver, and a Corsair MM300 Extended Mouse Pad.
