My Main Computer I bought in 2023

I have purchased a PC and will show you what and why I selected it. I am an infrastructure engineer in Japan and should be familiar with it.

(I am writing the price for your reference, but I buy it when it is the cheapest. Some of my purchases are made a few years ago when prices were lower.)

About my computer

I chose a small, high-performance desktop computer as our main computer.

• CPU: AMD Ryzen 7 6800H(8 cores, 16 Threads, 3.2–4.7GHz)
• Memory: 32GB (DDR5)
• HDD: 500GB NVMe and 4TB SSD
• Network: 2.5 Gbps
• WiFi 6 (2.4Gbps)
• HDMI: x2 (4K: 3840*2160)
• Dimension: 4.96x4.44x1.65 in (126x113x42mm)

This is Beelink Mini PC SER6 PRO 6800H and SSD.

Price

Price is important. It is considerably cheaper than a standard computer.

• Computer: 79,781 JPY = 796 USD at Aliexpress
• SSD 4TB: 29,724 JPY = 212 USD at amazon.co.jp

Which OS, Windows or Mac, or Linux

I use three operating systems. At home it is Windows. At work, I use Mac and a Linux desktop as a bastion desktop server. The operating system is the most important aspect of buying a computer. We selected Windows for the following reasons.

• You can use old software all the time.
• Some software is only supported on Windows.
• You can choose the hardware of your choice.
• If you buy a new computer and no longer need it, you can install Linux.

Desktop Computer or Laptop Computer

I chose the desktop because I don’t carry it with me and always work at my desk.

Dimension of Desktop Computer

Dimension is very important. I chose the smallest desktop possible.

4.96x4.44x1.65 in (126x113x42mm)

Which HDD

For OS: 500GB NVMe

This is the disk that came with my computer. 500 GB is the best size for the OS. If it were 250GB it would be a little small for many years of use.

For Data: 4TB SSD

I have added a disk for data. The cheaper 2TB would have been fine, but for the future, I chose the 4TB, even if it was a little more expensive.

Which Memory

My choice is 32GB (DDR5)

I have no problem with 16GB now, but I chose 32GB for the future. I am an IT engineer, so I run multiple operating systems on this computer.

Which CPU

My choice is AMD Ryzen 7 6800H(8 cores, 16 Threads, 3.2–4.7GHz)

A fast CPU is always better, but it is not very important to me. CPUs with higher performance are more expensive, so I choose based on performance and price.

Right now, it is Intel Core i7–6700T@2.80GHz, 4 Cores, 8 Logical Processors, but sometimes the load is a little high, but there are no major pr.

Network Adaptor

My choice is 2.5 Gbps

Normal 1 Gbps is fine.

What I already have

Monitor:

• 27 Inch, Dell S2722DC
  (28,296 JPY = 202 USD)
• HDMI x 2
• USB Type C x 1

I like the ability to change the height of the monitor. Cheaper monitors do not allow you to change the height.

Keyboard:

• Keychron C1
• Windows, mac
• TKL(Ten-Key-Less)
• Mechanical Keyboard (Red)
• Wired

After all, mechanical keyboards are easy to type on. I use the lightest red shaft to avoid hand fatigue. And I use the cable type so that I don’t have to worry about running out of batteries.

And this keyboard is compatible with both Windows and Mac. There is a physical switch to switch between Windows mode and Mac mode. Key tops can be changed.

Mouse

• Trackball Mouse
• Logitech M575S
• 4319 JPY = 30 USD
