GPU size case restrictions help?

[Daniel_1104]

So the core of my issue is my O11 Dynamic is too small. Please see the photo. So my mobo has 3 PcI slots and I have 2 GPUs. The GPUs are a 3 slot and a 2.75 slot card. So if I put my GPUs in slot 1 and 2. The first GPU gets choked off from no air flow, so ideally I need to put the 2nd GPU in the 3rd slot but due my case restrictions my case only supports a 2.5 slot on the bottom. 

 

The best solution is to probably buy a O11 XL which is kind of expensive. But i’m wondering is there some sort of PcI riser that lifts it up like 0.5 slots or can anyone else think of a different solution to have both GPUs in the case?

 

A clean look isn’t really required as this is temporary I need to use both GPUs, probably for about 2-3 months
