The only thing that can be salvaged from a BFL Single is the metal casing, the 2 fans and maybe you could sell the heatsink for scrap - a total value of about $5 at most (since their fire hazard PSUs are worth negative money).
This is why the Bitmain Antminer S1 upgrades are also useless.
The Bitmain s1 upgrades are useless because price is virtually the same as buying an s3. The upgrade is 240 gh/s for .46 btc, not really cost effective and an ROI is highly unlikely.
It would be really nice to see the jally back in action.
and Dr.G, i am still upset with you for not selling me your BFL singles =) j/k
Yeah well that is the same case with the S3 - they're basically recycling the case and maybe the controller board I think. Either way it proved to be not significant in cost savings.
If BFL were to use the jalapeno casing they would need to reuse the same heatsink and would need to find a layout of chips on a PCB that would fit under there. I think BFL wanted to move away from the jalapeno since it was too complicated with too many parts on the board.
As for the Singles, sorry about that. I really didn't want to ship them since it was a pain in the butt but the buyer made it easier for me to ship them and kids were involved and I always prefer new blood learn about bitcoin over us old farts (ok maybe you're not an old fart

)
