Question about Silent Hill 2 Director Cut's box

So the PAL version of Silent Hill 2: Director's Cut only released as a Platinum Hits game and I'm looking to buy a copy online. However, I've noticed that every offer online seems to have a blue case despite the game being a Platinum Hits game, which all normally have a silver case

My question is, did the game ever release in a silver case or did it only ever release in a blue one? I've found a rare few offers online with a silver case and I just wanted to clarify wether or not those are actually legitimate or simply case replacements. Or wether the blue cases are actually replacement cases.

Any clarification on this would be greatly appreciated
