Lets it juggle several apps and many browser tabs at once without slowing down.
Storage · space for your things
512GB
Room for your files, photos and programs — an SSD also makes everything open fast.

It's covered by the full manufacturer warranty, and if anything's faulty we help you sort it out. If it's simply not right for you, you have 7 days to return an unused item. See delivery & returns below.
By card through Payfast (secure, encrypted) or by EFT bank transfer — and EFT has no card fees. Your payment details are handled on Shopify's secure checkout; we never see your card.
Usually 2–4 working days, delivered tracked to anywhere in South Africa. A flat courier fee is shown at checkout.
