MSI 1070Ti Titanium - 2 slot card
This is my current setup - dead simple. You can't really see but I've moved the stock fans to the bottom for intake. Stupid thing is you can't fit the dust filter on the bottom if you're using the nifty rubber/pin mounting system. The pins stick out the bottom so the filter doesn't sit flush.
GPU reaches 65degC running furmark so I'm happy with that, but my Ryzen 3600 is sitting at 65~70degC with very light office use, which is no good. I'm now shopping for an AIO for the CPU. Going to mount it at the bottom and switch the GPU to vertical mount. Stock fans will go back to the top.
