Did not see that Corsair was not modular, thanks. My first build, GA-P55A-UD3, I7-860, GV-R577SO-1GD, G.Skill 4GB (2 x 2GB) DDR3 1600 F3-12800CL9D-4GBNQ, Western Digital Caviar Black 1TB 7200 RPM, Nzxt Hades and SeaSonic X650. Modular power supply a must for Nzxt Hades case. Despite Seasonic reputation it appears I have a DOA.
