Help adding an internal hard drive to G16CHR

[Akira_USA]

Hello,

In my previous computers there has been an unused power and scsi cable jack but not with this new computer that i could find. Also I was hoping to add a I am open to add a M.2 chip type ssd but i'm not sure if there's a spot on the motherboard to mount that into... Any advice how to add an internal hard drive, such as where to plug what into the mother board and where to possibly fix an extra hard drive in the case or what kind of hardware could help me do it or pointing me to the right place to look for this kind of advice would be extremely appreciated!!!

THANK YOU!

okey i saw now when i take off the non-transparent side i have access to open sata data cables (oops said scsi before) and a space where i can set a drive (not sure of a good way to physically mount it solidly there though) but the cables there are not what plugs into the hard drive. there are two different ones. one with 6 plugs and one with 2.. looks like i gotta just figure out the right adapter from that to a sata power cable.... so my main questions left are:

Is there a good way to screw in an internal hard drive into the desktop case? 

and is there a place to stick in and screw in a M.2 SDD in the motherboard somewhere?  thanks for any help!
