I see.  I really do not know whether or not your pc without hdd has the hard drive bracket included, but I searched around and managed to find someone selling this bracket.  in case you do not have the bracket, you can buy it.  it is somewhat amazing that Dell has P/N for almost every part.  notice that the bracket is either left or right handed thus having two DP/N.

Hi Everyone! I recently purchased an Inspiron 24 5400 AIO and now want to add a second SSD. Before I rip the back off, does anyone know if the HDD caddy brackets will be "parked" inside or will I have to buy them separately.  I have seen it both ways on the internet. Thanks for your help. Davie
