Just sent payment on the cube

How much did the Cambrionix 49 Port USB 2.0 Hub cost you?

Aren't quite expensive? $600 usd?

I bought secondhand for $200.  I think they were MSRP at $1000.   :o

Prices improved.

$1000?!? Thats insane! Is it 0.5 amp across all ports when fully loaded?

For sale - 93-94 GH/s in total or in parts.  Mining controller(s) not included.

Offers considered, be reasonable.

1 - Cambrionix 49 Port USB 2.0 Hub - withdrawn, repurposed
Manual, Antec True Blue 480W PSU, 24-Pin Adapter, Dual Corsair 120mm 90cfm 39dBA fans. 0.4BTC

Evidence suggests this is THE VERY FIRST 49 port hub ever used for bitcoin mining.

I've run it since June 2013 when the block erupters were coming online.  Pics from when I first ran it at 48 ports. https://bitcointalk.org/index.php?topic=7216.msg2764677#msg2764677

This hub is an absolute beast - far better build than the BE hubs.  I used to have one of those too - sold it and kept this one despite one bad port.  I bought this used and port 43 has been bad since I got it.  It could be fixed with a cable if you're good with a soldering iron.

Corsair fans are more than sufficient to cool all 48 ports and the hub itself - they're about 90cfm 39dBa.

PSU is a Corsair True480 Blue.  Rated 5V@38A.

Windows use not recommended - it's 24/7 perfect in Linux.  It has run great for me in xubuntu 12.04 since last June with as many as 48 erupters on it.

Ant - Not for sale
Dragon - Not for sale


Those who may be interested in the entire USB setup - it is tricky getting 4 different device types to play nice on one hub.  You'll notice in my eligius stats that my bitfury worker crashes intermittently.  Your mileage may vary - no tech support provided.  Also note that I moved my mining setup over the weekend, and there were several restarts of the equipment during this time.

Located in Pennsylvania, USA.  Cheap US shipping not included.  International shipping not included.  No customs fraud ie: gifts.

Buyer goes first or arranges known forum escrow at his/her expense.  I prefer SaltySpitoon, SebastianJu, or OgNasty.

Please, no trolling regarding prices/ROI - that discussion belongs in speculation forum.  USB mining devices are hobbyist devices.  Caveat emptor.  Offers considered, be reasonable.  Thanks!
