I got my motherboard and drives transferred over today. Also a new Seasonic 650w went into this build. The modular power supply worked out beautifully with 5 molex connectors and no extra cables cluttering the case and the cable lengths were perfect.
I switched from Ibm m1015 in the old case to a pair of Dell Perc H310s. As many know, I already had a little experience flashing these cards. I went with the Dells for better cable management.
I still can't believe how clean the inside of this thing is. My old build had power, fan and sata wires everywhere.
