Introducing 51nb's DIY Motherbord

The Nirvana of Classic ThinkPad

All about DIY Motherboard and 51NB

A warm Shenzhen welcome to our non-Chinese-speaking customers.
You are passionate about classic IBM laptops?
You have come to the right place.
Since 5th October 2017 we have been celebrating the announcement of Lenovo's 25th Anniversary ThinkPad. It's the official retro laptop.
It has some great features: lowish weight, a 7th gen processor, hot-swappable batteries.
However it cannot satisfy everyone
You prefer a 4:3 aspect ratio screen? So do we.
You want a sub-A4 footprint and a keyboard which goes to the edge of the palm rest? We understand.
You only need a trackpoint, and hate trackpads? Yep.
You like a high-density SSD (1TB, maybe 2TB). You can fit one.
You'd take 32GB of RAM? No problem either.

Disclaimer and About Us

  • “Our site does not sell the full laptop! There is no such ThinkPad as a so called "X62"/"T70" or "X210". We just build and sell simple motherboards. Anyone selling a full laptop does so at their own risk and without any warranty, encouragement or endorsement from Such business behaviour has nothing to do with this site.”

  • “You know a great design when you see it. In China we do too. Even if some of us were hardly born in the IBM ThinkPad era, those machines are becoming cult items over here. Just look at the passion on our user forum.
    You dream of putting new systems into classic shapes. We did something about it.
    Let's keep the flame of classic ThinkPads alive !”

    — HOPE

  • “The X62 is a love letter to the days of classic ThinkPads, ThinkLights, and 4:3 displays. The DIY-nature of the kit, plus the near necessity of an LED backlight upgrade, mean it is also a laptop mostly for hobbyists and those comfortable with tinkering instead of the average user.”
