My last Main Battle Tower PC was using dual Pentium III (OMG!). I was using notebook PC long time for my business and days off. I used mainly Windows for both my job and hobby. For instance, I called VirtualAllocExNuma() function on my job. So, I'm just noob for Linux. I just experienced built FreeBSD kernel and made home router on IBM PT-110 about 2 decades ago. I decided to make a new desktop Linux main station PC parts by parts by myself beyond a decade to enjoy Linux and check gnuradio w/RTL-SDR capability.
I checked current main PC parts stream and what is popular in 21st century from the several point. The following is my new self-build PC parts list.
| Parts | Manufacturer | Part No. | Remarks | Ref. price (jpy) |

At first, I estimated that total cost will be more expensive than that of PC-Shop assembled PC. But I surprised the total cost was much cheaper. Especially, hi-grade memory, fastest CPU, and powerful PSU are quite different.
Hyper threading vulnerability? I don't mind at this time!
Speculative execution vulnerability in the pipeline ? I don't mind at this time!
What I have to mind is Optane cache will work with GPT partitioning HDD. I use 2TB HDD until clear the problem for the time being.
