the optiplex 7070 is one of the series 5 optiplex pc.  the 7070 tower chassis looks remarkably similar to 3040 of the same series.  you may look on line to see what people did to the older 3040 case to upgrade gpu and get an idea of chassis physical limitations.  the 3 dimensions of 7070 is nearly identical to 3040. for example this video you can install a full length gpu double slot width about as long as the width of oem motherboard in 3040 or a bit longer (max length approaching length of chassis inside dimension close to 10.8"), likely same estimate for 7070.
