Hi everyone, first of all I wanted to appreciate the accurate and informative information regarding the replacement, but I had a question about changing the bottom cover. Since there is the number of mariculation on the aluminium cover, won't it be risky changing it? Or at least if you ask dell, will thay make another cover for you with your matriculation num? How much does it cost more less? Thank you in advanced for your gentle responce.

Does it have the same quality?
