Quiet $900 PC for Work & Gaming

I need some help putting together a quiet $900 build. I’ll be using it for office work during the day (lots of multitasking, spreadsheets, Zoom) and 1080p gaming in the evenings (single-player titles & some light online multiplayer).

My priorities:

  • Quiet operation (no jet engine fans if possible)
  • Reliable performance for years, with the option to upgrade later
  • Good airflow but not a bulky case

Can anyone put together a solid parts list for me? I don’t need peripherals or Windows. SSD storage is fine as don’t need huge capacity.

  • CPU: AMD Ryzen 5 7600 ($190 - $210)
    • This is a highly efficient 6-core processor on the AM5 platform, which ensures you have an easy upgrade path for years. It runs cool, meaning the fans don't have to spin as fast.
  • CPU Cooler: Thermalright Peerless Assassin 120 SE ($35)
    • Using an aftermarket tower cooler instead of the stock fan is the best way to keep the PC quiet. This model is legendary for being near-silent while performing as well as coolers triple its price.
  • Motherboard: MSI PRO B650M-A WIFI ($150)
    • A solid, reliable board with good power delivery and built-in Wi-Fi. It supports high-speed DDR5 RAM.
  • Memory: G.Skill Flare X5 32GB (2 x 16GB) DDR5-6000 CL30 ($105)
    • 32GB is the sweet spot for heavy multitasking and modern gaming. The "CL30" speed is the "Goldilocks" zone for Ryzen performance.
  • Storage: Crucial P3 Plus 1TB M.2 NVMe SSD ($70)
    • Fast, reliable, and since there are no moving parts (unlike a traditional HDD), it is completely silent.
  • Video Card (GPU): AMD Radeon RX 6750 XT or RTX 4060 ($290 - $320)
    • RX 6750 XT: Better raw performance for single-player titles.
    • RTX 4060: Extremely power-efficient and runs very cool, which helps keep the build quiet.
  • Case: Montech AIR 903 BASE ($65)
    • This case comes with high-quality 140mm fans. Larger fans can move more air at lower speeds (RPM), making them much quieter than standard 120mm fans.
  • Power Supply: Corsair RM750e (2023) 750 W 80+ Gold ($100)
    • This PSU features a "Zero RPM" fan mode, meaning the fan won't even spin during office work or light tasks, making it dead silent until you start gaming.

Quick questions - do you want a discrete quiet GPU (better for gaming) or would you prefer to rely on integrated graphics to keep noise and cost down, and are there any firm size constraints (mATX/mini-ITX) or a specific noise target you’re aiming for?

Thanks for asking!! I’d prefer a discrete GPU since I want decent 1080p gaming performance, but I also want to keep the build quiet. I’m flexible on case size as long as it’s not huge, and ideally I’d like the fans to be barely noticeable under normal use. Low noise is more important than squeezing every dollar of performance.
