this specification manual according to size of case indicates the size restrictions https://www.manualslib.com/manual/227528/Dell-Optiplex-760.html?page=15#manual

lastly on this subject, this page of the service manual show the layout of the board and the first thing that strikes me
is the number of PCIE x16 slots you have, which is 1... mean your limited to single slot video cards (can be double width that matters not, unless you have a Wi-Fi card installed on that slot # 13.

Be careful with the 760. There were 2 motherboards used, one of them only supports 2 Core CPUs.
If you have the Mini Tower aftermarket PSUs fit. Any others no PSUs, and Low profile GPUs only. Generally GTX750Ti are used since they work off of the original PSU. Single fan 2 slot cards can be made to fit by cutting the bracket in 1/2 and making sure the outlet air can turn left and exit the rear.
