Riser for optiplex 7070. A hole needs to be cut in the side of the panel. Be aware that normal M3 heat set inserts are to be used in all the holes in the model and are sized accordingly. Additionally, you may want to relocate the location of the mounting bracket as if you have a larger PSU the heads will scrape against the side making the side panel more difficult to close, though for me this wasn't too much of an issue. The support bracket shown is specific to the ASUS 3060 Ti, so if you need one for a different GPU you will need to make one. The offset from the backplate to the side panel (the gap between the GPU and the side panel) is about 16mm, in case you plan on making your own support bracket. A cheap 200mm Asiahorse riser from amazon was used. (gen 3 as optiplex mobos of this generation do not support PCIe gen4).
