I'm looking for a GPU-upgrade that will fit in my G20CB. Preferably a 1660 Super (or Ti).

I already upgraded the default GeForce GTX 960 to a Radeon RX 590 (Gigabyte), but that one broke down.
I was looking for an alternative around the 250 EUR price range and bought the MSI GeForce GTX 1660 Super Ventus XS OC.

Sadly that one didn't fit because the metalic lid on the back didn't match the dimensions of the card. So I had to send the card back.

Does anyone have a 1660 Super (or Ti) fitted in his G20? Or are there alternatives within this price range?
