We’ve been out of stock on expansion units for some time due to an issue with our sheet metal manufacturer and the prototyping of new cases. We are currently fixing this issue and should have units available soon.
Email us at support@micro-nova.com if you’d like to be added to our temporary mailing list and be informed once there are units available. Just mention you’d like to be added to the list and it’ll be done. Again, this mailing list will be temporary, one time use. You can expect to not receive any spam by signing up and will only receive an email once units are available.
We make them in batches, and so emails will be sent in batches in a first-come-first-served basis. This mailing list will be the best and possibly only way to get an expansion unit within the short term due to demand.
Thanks for your understanding!
