    Good MB for the budget but the my GPU does not allows me to connect the caseusb cables
  

*by J***. on Reviewed in the United States on September 21, 2021*

Good MB for the budget but the my GPU does not allows me to connect the frontal usb cables as that slot is too close to the PCIe slot for GPU, it's literally impossible to connect them without getting my case cables interfering or getting in the GPU fans, that is so annoying even tho my GPU is an RTX 3070 MSI Venus 2x and that is not what you would call a big chungus card.that's the reason why i'm giving it 3 stars instead of 4, I'm not able to connect any usb ports cables on that slot anymore unless i change my gpu, and considering the times of shortages we are experiencing, that's not gonna happen in at least 3 years.
