Here, I know them personally and have been technically familiar for years with everything to do with computer technology, my relative is the boss and has immense specialist knowledge.
He advised me against my ready-made PC, but didn't listen to him, unfortunately and ordered Otto. So finished pcs are nothing, I paid twice as much as necessary.
Well my relative runs the site, was also a gamescom exhibitor and clearly makes authentic pc compilations, you can give us a call.
Hi, I have my PC from Agando. There are ready-made PCs that you can convert if you want. I know the one I'm sending you as an attachment is too expensive, but they often make discounts. Got the same and only bought it for 970 euro.
Many greetings, Niels

With the budget I would take the system here:

Then just choose a better processor.
