Manual for new computers is online at Dell Support. Alienware Aurora Ryzen Edition R14 Service Manual (dell.com)
Hello all! I basically know nothing! I'm looking for some assistance with installing a Dell 2TB 7.2k RPM SATA 512e 3.5in Hard Drive I got from Dell into my Alienware Aurora Ryzen Edition R14 Gaming Desktop.  It came with a single SSD and no HDD.  I'm looking to increase my storage capacity.   The HDD arrived with no instructions so I do not have the first clue as to how to install this into my PC. 
Aurora R14, how to add 2TB SATA HDD?
