There is a blue SATA cable routed from the mobo to the 3.5" HDD bay in the front top, behind the PSU swing arm.  If you don't have an HDD it is spare and can be rerouted.  If your R11 came with an HDD, then you need to purchase an additional one.
Hi everyone, I just bought a R11 with 3080 and am very happy about it. I tried to add a SSD in it, but couldn't find the alimentation cable (the little one, blue i think). The other one was really visible... Is it hidden somewhere ? Do i have to add it (but none was given with my new SSD) ? Thanks, PaBa
