E5-571 compatible HDD and RAM

Hi all. I have an E5-571 but the lid and hinges are wrecked. Tried several repairs but now seems beyond hope. Everything still works ok but the lid is only supported by 1 hinge. The bezel is wrecked.

My question is, I have a 1TB HDD and 12G Ram - what other models can I transfer this into? I'm looking to see if I can get an 'empty' one cheap on ebay, but need to know what other models are compatible. Many thanks.
