If your referring to the post icons and the white edging showing then this is due to the post icons being saved out for a white matted background.

You'll need to save the set out in a black matte or transparency and the white edging around the post icons will disappear.

Check this post to give you an idea in what I'm saying and you'll find that this issue is easily rectified. Matte background thread.

If you referring to the white borders surrounding the data I'm quite sure the settings are in your styles main css (but don't quote me on that) I would need to check.

Edit: If it's the border surrounding the data/ images I think the area you need to edit is the Panel Surround. Although I'm sure lynne will pop in and correct me on that.
