Im a bit late in posting as ive had this rig for almost a couple of years now. i have dell 9020 ssf and I managed to squeeze in a Geforce 750 ti.
A bit more aesthetically pleasing than having the psu hanging loose
I did have to take the side off my Dell stock power supply and luckily the GPUs fans fit inside the PSU. haha, in summer i have to have side off the pc else it can get a bit toasty and I get artifacts or glitches, its been really hot this year but normally it runs just fine fully closed up.

The GPU that fits in is a - [MSI GeForce GTX 750 Ti DirectX 11.2 N750ti-2GD5TLP 2GB 128-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card
I had to a get SFF bracket for the graphics card off amazon, You lose the VGA when you replace it with a half height bracket that includes HDMI and DVI.
I also had to unscrew and slightly tilt the PSU
