Preface

I assembled this computer over winter break (Jan~Feb) in 2025, when I could not play many games with just a light laptop home, so I thought of assembling a computer. My requirements for this computer were:

  1. small enough and light enough;
  2. as low a price as possible;
  3. have decent performance for gaming;
  4. have Nvidia discrete graphics card and support deep learning.

Hardware Configuration

After searching for many low-cost installation tutorials online, I settled on the following hardware configuration:

Hardware

Things to note

  1. Nvidia P106 is a compute card, there is no display output interface, the CPU must have a core display; in addition, Nvidia does not provide official drivers for the P106, you need to install a third-party driver on Windows (Linux does not require a separate installation).
  2. My extra spending: replaced with two brand-new 8G memory sticks, costing ¥47.5; graphics card extension cable, ¥33.44; SATA 3.0 cable, ¥1.9; motherboard buzzer, ¥1.74; SATA to 6PIN power supply, ¥2.84.

Total ¥545.12 (if do not change the memory stick, the total ¥497.62).
