Has anyone received a reply recently?  Have all the parts except the x5 boards.  Am eager to build this.  If anyone has the x5 or x6 boards would be willing to buy at a good price.  

I've sent a request but haven't heard back yet.

If they want to get more orders together, I'm game.  I emailed them from their site and waiting for a response.  I realize this could be used to upgrade my C1s, and I have a pile of them.  So I could put in a big order for these if they work in an Antminer C1.  They should.  I think they are all the same boards and the C1s just had the water cooling blocks instead of the fins. 

Guess not.

any luck ?

I received an email from them recently.

As of 10/19, they quoted price of X6 kit of $950 USD, prepayment, with a 6 week lead.

No mention of the X5 kit.

are you going to place an order ?

btw still no response from them...

I was ready to pre-pay (in any form, be it BTC or USD), but after 2 weeks of conversation they ended up saying that they were "unable to serve an order". Kinda strange business model, to say the least.

finnaly, they replied to me (same prices)

correct me if I'm wrong, but If I understand right, they said that you must order 10 units minimum for international delivery, this is not applied for customer pickup in Ukraine

They got back to me today to say they don't ship to the US currently and don't have a reseller here. If enough of us are interested we might be able to place a large enough order to make it worth their while, though. PM me if you're interested, I'd be good with coordinating (or buying in if someone wants a bunch and just needs a few people to jump in, either way).

I have slightly updated this review and there is now also a nicely formatted version available (.pdf document).
