I'm ordering a new SB rig tonight and am currently tossed up between MSI and Asus Z68 GEN3 boards but if someone else has a different suggestion SPEAK UP!!!!
Case - I'm going to see how I like the new stuff in the trusty old Antec 900. If it just doesn't suit me anymore I'm grabbing a Corsair 800D
Power Supply - Keeping my Thermal Take 850w Black Widow. It's been rock solid
Sound Card - X-Fi PCI-E
Video Cards - 2x GTX570 2560MB
CPU - 2500k
CPU Cooler - Zalman CNPS9900MAX-B
Memory - 8GB G.Skill 1600 (even though in a 64bit environment 4GB is a bit faster)
