The X-3 has always been a 2x3u design.

No information on the X-1 at the moment. I'll see if I can dig up some more info.

If you ordered a miner, the order itself doesn't reserve your placement. We reserve placement based on the time you paid.

If you're having an issue with your order, please submit a ticket (one) and then PM me the ticket number so we can track it.

If you have a ticket that's been updated without a response, PM me the ticket number.

Don't expect a response via bitcointalk. I have a 5 minute delay between messages and that's just enough time for me to find another task. Hopefully that cool down period goes away soon.
