Will a MSI gtx 460 cyclone fit in a biostar mcp6p m2+ and a Rosewill R

I know that the case i have is a micro atx mid tower case so it makes me think that mabye the gtx 460 will nit fit in my computer. I curently have a gt 240 so if the gtx 460 is smaller (I dont think it is) thats great. :bounce:
