Can you take 1 AntMiner C1 and 2 S5's and combine them? YES

[IITravel01]

You will get a C2 with 4 S5 blades (and 4 leftover C1/S3 blades and 1 C1 controller as well as 1 S5 controller).  Just did this, haven't got it running yet, but you do not need any other items to do this except maybe a pair of these http://www.amazon.com/gp/product/B00B46XJRK/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 as the controller board will block one of the PCIe power connectors on each side (internal boards).  The controller board will have to just sit on top and the two internal cables that connect to the inside blades will be short and tight, but if you take it easy they will fit.  You will have to use the controller board from the S5 as the cables and connectors are different than the ones on the C1.

Can you hash with the C1 blades? I want to see some pictures.

[Shazam!!!]

Please do post some results when you get them. This is very interesting.

I'm putting the leftover C1/S3 blades together with the leftover S5 cases and heatsinks and should have them hashing shortly.  Wish this site let you post pics. straight to the message board rather than a link from another site, now I'll have to figure out my photobucket password again.

The C1/S3 blades (4 of them are running now), no problems for the last 5 minutes at least.  Room is 91 degrees F and the temp. shows 50 degrees C with no HW errors.

Update, only seen one HW error show up so far.  Temps range from 45 C (in a room in the 70's F) to 52 C (in a room in the low 90's F).  So far, running about 1,000 Gh/s (avg) at stock speeds.
