I just received my copy of Cuplex Kryos HF AM3 and it was looking as expected, until I've checked the bottom part. After removing the sticker I was quite shocked. On every photo everywhere it has a nice polished, shiny natural copper color. Mine is more like purple excluding the area near screws and small vertical line near center when it looks as expected. This pattern is also visible at the inner part of the sticker as color blue. See the photo. Is it normal or corrupted somehow ?
