how to put a second hard drive in mac mini mid 2010

There is a flush square connector connecting the HDD to the main board. Remove the fan duct by removing its T5 screw on the bottom (the crescent shaped black plastic to the left) It takes a bit wiggling to get it out of there. Flip the perforated plate toward left without removing the WiFi wires. Remove the perforated stainless which holds the WiFi antenna by unscrewing the two outer screws then removing the smaller flush screws on the same plate holding the HDD in place (use Torx T8). Remove the black bottom plate, no need to remove the memory modules, remove the fan (only three T5 torx screws), gently detach the connector by pulling on its wires. Just to replace the existing hard drive with an SSD is much simpler on the other hand. OWC has excellent videos on the subject but they can be misleading because they 'add' a second drive to the Mini and that takes an involved surgery, necessitating the removal of the logic board. Easier than you think because the hard drive is located just under the perforated stainless plate.
