I have a Precision 3260 Compact (https://www.dell.com/en-us/shop/workstations-isv-certified/precision-3260-compact-workstation/spd/precision-3260-workstation/s106dpt3260us_vp) with no standalone GPU. I also have an aging gaming desktop with a GTX 1070 and an i5 inside. I am trying to figure out a way to get the 1070 to work inside the Precision and it's driving me nuts.

The Precision doesn't have a standard micro-ATX motherboard, so I can't simply mount it in my larger case. Even if I could, the pcie slot is much shorter than the standard. On top of that, the GPU is longer than the entire case.

I'm willing to get creative, but I'm out of ideas.
