These models include:
• Predator Helios 300 (G3-571, G3-572, G3-573 and PH317 models)
How can I get the HDD Kit?
If you live in the United States or Canada, and have an Acer Predator Helios 300 that does not include the HDD Caddy and SATA cable, you can request the Kit on the following link: https://csapps.acer.com/kit-request/#submit
If I am outside of the U.S. or Canada region, can I still get the HDD Kit sent to me?
If you purchased a US or Canada unit and had it shipped to your country, you would need to contact your local Acer Support to inquire about ordering these parts in your country https://www.acer.com/worldwide/
Can I use a freight forwarder to ship the HDD Kit to my country?
Unfortunately, we cannot mail to freight forwarder's addresses. We need a physical mailing address in the U.S. or Canada to have it sent to, then they would be responsible for mailing the parts to your location, at your expense.
How can I install the HDD Caddy and SATA cable once I receive it?
Please follow the instructions on the following link for HDD Kit installation: https://us.answers.acer.com/app/answers/detail/a_id/47006
