Remove link from boxes

I was wondering, if it is possible to remove the link function of the entire boxes (on the front page) and just use the more link at the bottom of each box? As it is now, the entire box is a link to the post. I use the frontpage as a post collection with excerpts, and want to be able to link to each author as well in the box beside the post. And this is not optimal when the box with the exceprt itself is a link to the post.

Thx in advance.
