Here's mine, that I've been using the last 2 years.
Some essential PC specs:
Intel i7 7700k
GTX 1080 Strix OC
16GB RAM
Peripherals for playing:
Razer Cynosa Chroma Keyboard (primary)
Some cheap ass XBox fake gamepad (only for certain types of tracks, not pictured)
Samsung C49HG90 49'' curved monitor.
Runs TM like butter, though hoping for a better optimisation for ultrawide soon.
And ofc the cherry on top, a mean machine of a lean back chair from 1997. Definitely don't want to play a boring map on it as it's comfortable enough to fall asleep on it instantly.
