Glad to hear many of you say it will fit. I thought it would but wanted to make sure since I read the following:
"The Antec One supports video cards up to 10.5” (266 mm) long and CPU coolers up to 6.1” (155 mm) tall."
And this from newegg:
"Heatsink Dimensions 120 x 79.7 x 158.5 mm (L x W x H)"
That sounds to me like it wouldn't fit. Either I misinterpreted that, or one of them just got it wrong.
I'll stick with my plan to get the Antec One.
Thanks for the help, everyone.
