This was my first build about a couple years ago, and I'm pretty happy with it. The only thing I wish I had was a beefier GPU and maybe a better CPU, but I rarely notice it since I have so many old titles to get through still. I did get a PiMax 5k+ and it definitely needs more power if I want to get consistent frame rates without throttling, Black Mesa looks great in VorpX though!
CPU: AMD Ryzen 5 1600 @ 3.4GHz
Cooler: Scythe Mugen Rev B (Overkill, but whenever I get a new CPU I'll be ready, and who doesn't want a massive piece of steel protruding from their PCB? It also barely ever gets over 1,000 RPM since the radiator's so massive so I never hear it)
GPU: MSI RX 580 8GB Gaming (Hoping for an RTX 3060 Ti when stock finally becomes attainable, but that could take awhile if scalping continues to be feasible and if demand stays the same)
RAM: 16 GB Corsair DDR4 @ 3000MHz (From what I understand, frequency is big for Ryzen, so I'll probably get higher clock speed whenever 16 GB becomes obsolete, worst case I always have New Vegas)
Headphones: Sennheiser Game One (Cheapest headset I could find that was reported as durable and having a serviceable mic)
PSU: Corsair CXM 550W
Motherboard: MSI B450 Tomahawk
OS: Windows 10 Standard
Monitor: ASUS 1920x1080 144Hz (1080 works great for me since I'm not too far away from the screen, and being able to run programs at 144 Hz is such an improvement, though I hear after 200 FPS the difference starts to become negligible, 90 Hz I think is still a massive boost though, 144 is just all I'll ever need)
Storage: 1 TB Samsung 860 EVO, 512 GB Samsung 850 EVO (Boot drive), 256 GB NVMe SSD (unsure of the type, salvaged from laptop, I wanted to get a high capacity HDD but I'm too attached to my PC being dead quiet besides the GPU)
Mouse: Razer NAGA left handed (I have nerve damage to my right arm so having a left handed mouse with 12 buttons makes everything so much easier, and I can already feel the pain of my future arthritis being alleviated, it was very pricey though, and clicking with my pointer finger on the right button feels so weird. I feel like I've been conditioned to live in a lower form of UI interaction)
Keyboard: Logitech G610 Orion Cherry MX Brown (Can feel a little bit loose but the mechanical switches are still nice)
Case: Corsair 200R (Looks like a monolith, I love it, though I wish it had more SATA ports, a measly 4 is all it has)
