Hello. Many of the older thinkpads were regarded as being peak for the ability to repair and easily see into them at both the hardware and software levels.
I was wondering, what PC, if any, is similar in this regard? Aside from building your own PC ofc. Any opinions are welcome. Thank you.
Are you looking for a laptop or a desktop machine?
Framework laptops seems kinda cool but they don’t ship to me yet so I have no personal experience. https://frame.work/
Many computer stores offer to build your computer from parts for a fee, that would give you the custom PC without building yourself.
Can recommend a framework as a laptop. It also allows you to just use the motherboard as a standalone machine. But it being laptop hardware and only having one m.2 slot might be a deterrent for OP.
For a laptop, Framework is absolutely peak for repair and upgradability. They even offer newer generation motherboards that continue to work with older generation framework laptops. Enabling you to upgrade the core components while not having to rebuy the chassis, monitor, etc.
For a desktop, either build one yourself or buy from one of the companies that assemble it for you. Companies like Maingear.
