Edit: Alright, I'm home from work, links added! Let me know if I missed any. All of these were or have been available with Amazon Prime when I bought them.

Mobo: ASUS ROG Strix B450-F
CPU: AMD Ryzen 7 3800x
CPU fan: Wraith Prism
Note: This was included with the Ryzen 7 3800x which I was not expecting when I ordered it! The Wraith Prism can be synched with Razer Products so I have them all change color to my music.
GPU: MSI GeForce GTX 970
Note: The only part I kept from my old PC. GPUs are expensive, yo.

Mousepad: Timor Pro Gaming Mousepad
Note: Sometimes these large graphic mousepads come out a little low-res, this one is NOT and I'm super pleased with it!
Chair: Hbada Office Chair
Note: The chair was only $130 when I bought it and it had Amazon Prime available, don't overpay if you're looking at it!
Final Notes:
I put contact paper on my desk surface, the desk itself is the same! I wouldn't recommend the brand of contact paper I got, it's already torn in a few spots just from normal wear and tear. I bought one that was wide enough to cover the width of my desk without using multiple pieces, and that was definitely worth.
