Hi, everyone, my name is Holstein, I was a reviewer on PC motherboards, and a big fan of ThinkPad laptops. I like hiking if I have the time, but I am really busy now since I am taking an MBA course.
I've been programming since 2005 and been a professional game developer since 2013.
I've recently turned my home office room into an electronics workshop and I now have a range of computers to tinker with and restore.

Hi, I'm new to this forum.
My second system was a Pentium 3 733 MHz processor.
I'm not a hardware expert, but I'm crazy about computers, laptops, phones and tablets. I like to repair in my free time, laptops, tablets and phones, various home appliances. I like outdoor sports, hiking, vacations. I hope to help this forum to maintain it.
