If you really want to go sketch, for certain Dell power supplies you can recover just enough clearance to install an RTX A2000 or low profile GTX card by cutting through the power supply casing. Obviously, separating the casing from the power supply during this process, ensuring the metal of the card is not touching the PSU and ensuring there is another method to separate the PSU and GPU is critical.
For extremely obvious reasons, I strongly recommend that you don't try this if you don't know anything about it. For mine, I made sure it was manually discharged, left it for a week, then carefully pulled apart the PSU casing to determine if there was even enough room for a cut to work.
Dell only offers the PCIE x16 slot on top for their Precision models, but with this I was able to fit my RTX A2000 and Elgato 4K Pro MK2 in an Optiplex 9060.
