If you only opened it up without touching anything inside, that CPU fan is clearly not mounted.
It's mounted.
Bingo!
It is the worst design I've ever seen. The motherboard PSU connector is some kind of 8-pin connector.
Oh, and there are no SATA power connectors on the PSU. It literally only has two connectors, the 4-Pin and the 8-Pin that connect to the motherboard. There is another connector on the motherboard just below the 8-Pin connector, that is where the SATA power connectors come from.
On top of that, they put in an absolutely anemic 290w power supply. So if you want to add a decent graphics card, forget it. The power supply won't handle it, the power supply doesn't even have a 6-pin PCI-E connector, and forget about replacing the PSU obviously. But most importantly, if the PSU fails replacing it will be a real pain, and likely extremely costly.
I recommended the client sent the piece of shit back.
Things I see:
- propietary board with propietary connectors
- Is that chipset naked?
It is naked, but it is only an H81. I wasn't too happy about no heatsink on the chipset, but I touched it when the machine was running and it was warm to the touch but not hot. So guess the heatsink isn't technically necessary for H81.
