Is it worth taking this config with Avito? What problems might arise?

Question

Computers

I found such a system unit on Avito, the only thing that confuses me is that earlier the seller sold a lot of components and this config looks very profitable.
Such a new mother costs 18k, 32k percent, plus a scalp and other components.
I want to take it from delivery, so I can’t check anything.

config

Процессор Intel i7 8700K скальпированный
Материнская плата Gigabyte Z390 Aorus Ultra
Кулер Bequiet Dark Rock pro4
Озу Kingston HyperX 16gb 3466c16 на чипах b-die
Блок питания ZALMAN ZM850-GVM
Жесткий диск SSD Nvme Intel 660P 1Tb
Корпус Cooler Mastel Elite 371
5 кулеров на корпусе ID colling и Arctic freeze

The percentage and the mother are also sold separately, but other components are also quite suitable for me,
plus, as far as I know, Avito delivery allows you to return the goods within a day, if you prove somehow its inoperability, therefore it will be easier to prove with a working PC than with a percentage + mother.

What problems may arise?
The assembly without a video card, the only thing that comes to my mind is that the processor was launched at unacceptable voltages
, as a result, it was spoiled, therefore, when working at 5-5.1 GHz, a blue screen will fly out.
I can find this out in a day.
Or, for example, they put on a cover from another processor, well, this is already quite primitive.
What else could be wrong? These video cards are warmed up after a dump, and so on, but here there is little you can think of.
Is there anything that I cannot detect on the first day of use?
Has anyone had experience returning such goods after Avito delivery?

Answer 1

It’s better to take a system unit on Avito for 5 thousand. Still, losing 5 thousand is not as scary as 55.

Plus, as far as I know, Avito delivery allows you to return the goods within 24 hours, if you prove that it is somehow inoperable, therefore it will be easier to prove it with a working PC.

Avito does not have fraud protection. At least pay after receiving, at least order delivery - if the goal is to deceive you, you will be deceived.
I would either buy on Avito in my city (with verification), or buy in a store in parts.
