The manufacturer has to honour the warranty regardless of if the retailer has gone broke. Contact them directly and if they're anything like Acer follow up regularly and expect to wait ages while it's repaired. No experience with Toshiba myself.

I'm pretty happy with the Metabox I bought last year, no issues so far and put together in Perth, except for making the mistake of putting Windows 10 on it. Chrome does not work on it any more, who knows why? Kind of wish I'd gone for a Linux based operating system now I've learned how easy Raspberry Pi's are to work with.

Work uses professional Dell, seems to go forever, the 4k box I use is great! I bought a cheap Dell when I was at Uni, lasted 15 months before the motherboard died. Was not worth fixing. Then I had an Acer, their customer support/ warranty handling wasn't great when the Cinepad went on it at 2+ years, waited 5-6 weeks to get it back.
