A question about external drives

i already have 2 drives on my computer with room for no more, i was wondering if there was a kit to turn a dvd burner internal drive into an external drive. also would my computer recognize it as a drive. any help? :cool: or could anyone suggest a good dvd burner external drive.

i was thinking about this one http://www.newegg.com/Product/Product.asp?Item=N82E16827106011 or this one http://www.newegg.com/Product/Product.asp?Item=N82E16827106016
