Which laptop can you recommend, where you can change almost everything (CPU, GPU, RAM)?

Hi, I'm looking for a laptop where you can switch off the main components if possible. He also likes to be older. Price range up to 600 euro. Do you perhaps receive recommendations? I only want to exchange CPU, GPU and RAM.

I have to tell you sadly that there's no laptop in which you can exchange more than the RAM, everything else is soldered by the manufacturer.

This works only for very few, extremely expensive high-end laptops

What's that good for?

Buy a device that is well equipped. Then the 5+ years and then you do not want to spice up the old device…

And old zmB. Thinkpads, but just the oentium sockell or whatever sdrin idt
