Is that a big GPU in a tiny case? That is a good way to overtax the usual small case PC power supply or overheat and quickly kill parts.

-> Since other graphics cards fail then my bet is something blown in this unknown but apparently micro case PC.

Can this be put into a normal size case with a good size PSU?

I can't tell what that is.

The page shows something unrecognizable. But as it's working, it appears to be case closed.

It was working but its since stopped

I was saying it did work fine but when I tried to Set it up at home it didn’t work. So it’s probably not an issue with the build especially because it’s a trusted pc brand pre built not custom built.

Even trusted pre builts can be problematic.

All I see so far is a known recipe for trouble. Big GPU in a tiny case. Your seasoned techs and builder won't do that.

What should I do?

It’s just the owner had it for a good year or so and it was working hours before I brought it home. What would you recommend I do? Buy a bigger case and move the components into it? Or maybe a new motherboard? Or try something else. What’s to your knowledge most likely the problem?

And exactly why we don't build units like that.

The small case often runs the parts at high temp and everything ages faster.

Now this is not a problem with gamers as they tend to change out hardware every few years but if you don't get it new, you miss out on the good years.

Since the parts may be iffy due to the high heat you can't know what is good or bad. You move to a big case and treat it like an old PC. Swapping out what you suspect.

-> But this story sounds like it's a recent buy. Call it a lemon and get a refund. If it works for them, that's fine but it's not working for you and you could have a machine with few good parts or years left.
