Parts from Aliexpress

We've seen a lot of cases of frauds (mostly GPUs) on Ebay and Aliexpress, but they're generally both unreasonably cheap and very obvious - wrong outputs, half the price, wrong size etc.

Judging from the images and price alone, I'd say this is probably OK. Getting a GT220 and slapping a "GTX780" label and new cooler on it is easy. Making a board with an LGA1150 socket and the right ports in the right places is a lot harder. The price is also not unreasonably cheap.

However, you're still buying a used board for an obsolete platform. This is rarely a good idea.
