Here is the link:
https://www.amazon.com/Cooler-Master-Tempest-GP27U-Adjustment/dp/B09Z6HV9LF
for $799.00
List price: $1,099.99
If you click the buy now on their website:
https://www.coolermaster.com/catalog/setup/monitors/tempest-gp27u/
it goes to that above page at Amazon.
edit: Weird, updated the above information, as I was getting an older Amazon page, with an $879 price.
Bump.
Per looks like someone at Cooler Master posted on this Amazon page that the monitor is set for an "early September" release.
This link works for me.
