You said you have a 7010 MT. Mini tower means it will take a full height card but it has to be short. That is why I have a GTX970 mini. It is full height but 1 fan.

Here is a link to the first one on ebay. https://www.ebay.com/itm/Gigabyte-GTX-970-4GB-OC-Mini-ITX-w-SLI-adapter/174243807192?hash=item2891bd7fd8:g:jOsAAOSw9uxejM9Y

Again, that is the first one. I am only linking it because it illustrates something similar to what I have. I am not suggestion you buy this one.

Does your computer look like this? https://www.cnet.com/products/dell-optiplex-7010-mt-core-i5-3470-3-2-ghz-4-gb-500-gb/

If not then you don't have an MT.
