It won't be an easy move since the SFF has some proprietary connectors. The page here has more information as does this page. Having said this a user has a video here that shows how he did it, but I am not sure it was a 7010 SFF MB.

sell the SFF

buy MT

end the pain, 

Mouting and cables and everything else is not the same.

This is not going to work.

GPU why, tell 1  reason for needed any GPU,

reasons matter, BIG TIME

dreaming of some unstated game?  IDK.

gt1030 WORKS in all models except USFF micro and AIO.

but would make a good youtube video doing that and failing,

make money doing wrong things on the tube like most do there.

why not make PC from DIY ,  by Asus, z270prime or better, (wow even real documents with it and QVL) wow!

buy a 10000x better case, endless sold now,  some are SUPER Great and run 10x cooler than most PC made.

then pick up GTX1650 GPU.

TX550m  up PSU from Corsair, semi modular.

Get a real full sized desktop so you can upgrade easy, and never buy any DELL with BTX mobo inside, ever.

You can do it but it will require to cut of the stock cooler connector to use it for your other cooler as well with the rear fan. You will need a small standoff for the big screw on the motherboard. Also when placing the gpu the  shield can break of a resistor or a capacitor, i removed it. And also the i/o shield you will need to get one or cut the one off. But before any of this make sure the case screws fit. You will also need to bring your front panel and power cable.

Before:

Readeon HD 6450, i7-3770, 16GB RAM, 1 HDD, 1 DVD Drive, stock power supply.

After:

GTX 750 ti, i7- 3770, 16Gb RAM, 2 HDD, 550w power supply.

im trying to do the same with a 7060 sff that i got for cheap(250$) i have a 7010 mt i7 3770 1tb evo 500wpsu 22gb ddr3 1600 and a 1660s that works great but..... i like tinkering around with these optiflexs ... so the upgrade would be fun.. if i could get it in a better case. anyway , i dont think these guys are being OPTImistic enough. with a dremmel, quit 120m fans, and some cheap wires of amazon. im pretty sure i could make her function and look pretty sharp cheers!
