I'm attempting to modify an OptiPlex 9020 sff but due to the pcie 16x slot being at the bottom and furthermore being blocked by the psu the biggest gpu I would be able to get would have to be a single slot gpu. I could use a gpu that is 2 slots big but it would have to be placed in the 4x slot which may lower overall performance. How much of a performance drop this would create I'm unsure, however if I were to use a strong enough card that might counter the effects I'm not really sure.
But primarily I'm looking for a gpu that is 1 slot big that will fit in the machine and isn't ove
