Best laptop for 750 euro?

I have ever asked a similar question, but did not get really helpful answers.

I'm looking for a laptop that has enough power for image editing in Photoshop and video editing in Premiere or After Effects.

He should have at least 8 gigabytes of RAM, if possible upgradeable.

Battery does not have to be the best but already mediocre and cheap.

It is also very important to me that he is not too big and not too heavy.

But I do not want a plastic bomber.

My recommendation would then be a refubished zbook 15, e.g. Something like that in the way (as an example, which is too high):

A zbook has a lot of RAM, is solidly built and well upgradeable.

You just look if the values are the highest there's. After that calculator / Lappis are also searchable online.

Can one make alternatives there?

Next question: Upgradable,

Then size

Then weight

and seeks the healthy medium

There are just too many to give concrete examples.
