I don't own this case, but I've done a lot of case modding so I feel like I carry some authority in this field
first off the door lights won't be hard to get it, it's just a matter of getting the new ones in. Generally on 'cheaper' cases like the one you want it's just a LED that's hot glued into a little plastic bracket.
The light on the bottom is most likely the fan. I've never seen a grill with lights in my days.
