Yes! I've found this take a look: http/www.2ndhddcaddy.com/acer-aspire-e5-571-37sy-2nd-hdd-hard-drive-caddy.html
What i don't know is, in the part that is mentioned "thinkness" says both sizes (9.5 and 12.7). Which one is?

Some 2.5" drives are thinner (9.5mm) for the newest laptops and netbooks. Both sizes will fit. The 9.5mm usually come with small spacer to fill gap.

Ok! I'll go for the 9.5 one so. Thanks !
