No, Calyraen computers are out of stock right now. That covers the whole range: Stratus laptops, Vantage desktops, Atlas workstations, and Forge servers.
You can still browse the full lineup and read the specs at /products, so you can figure out which machine fits you for when stock returns.
If you want to ask about availability, open a ticket at /support and pick the Sales option. The team can answer questions there, though we can't promise a restock date.
