Got my Vengeance 5180 a few days ago and am loving it! Investigating the specs from the motherboard, am I right that there are 4 SATA-600 slots, one of which is occupied? I'd like to add a Samsung 860 PRO 4TB 2.5 Inch SATA III Internal SSD (MZ-76P4T0BW), and I think that will work. Am I correct? Thanks for your help in advance.
