11.5btc

Only a couple hours left to bid! Highest bid is 11.5 BTC. Are you going to let CJPOLO walk away with such a bargain? Cheesy

How can you fix these shorts with an soldering iron?

Or wait now.. it's components on the other side we see..

Yes, those are just decoupling caps on the other side of the board.

You know you need fairly advanced equipment to either salvage the chips, or to reball these?, It's not something you do with hot air, or your pancake griddle..
I'd guess that most of these boards shouldn't need reballing at all. The assembly house did x-ray inspection on the BGA, and took care of reworking any BGA failure. What we're likely to see here (and I haven't been able to personally inspect these boards either) is failed oscillator or voltage regolator modules/soldering.

if you are not going to make it anymore why you don't open source it instead of keeping the file collecting digital dust Tongue

This.

Also, 11.1 btc.

TBH 7.6 BTC is still much undervalued for this.
If customs wouldn't be quite as picky as they are over here, I'd bid like 50 BTC on it.

Board retail price would have been about 75 BTC, and I know MMQs are currently being sold for about 50% above retail if you want to get one quick, so that would still be an awesome deal even if you can only fix half of them. (And remember, a bunch of them are working at half their hashrate already!) Let alone all the other stuff in here. The FPGAs alone are worth another 5 BTC.

So if you can get all of the boards to work, this whole package would be worth around 120 BTC.
So if we deduct the raw FPGAs and ignore the various other parts, the 2.6 BTC left in the current bit roughly account for one working FPGA. I'm fairly sure that more than one will work out of the box Smiley

The discount I think rightfully should be pretty HUGE as the boards come with zero guarantee of working. You can also buy the x6500 working with seller warranty online at forums etc. for under BTC2 each so I am not sure where you get the BTC75 or BTC120 from.
Tell me where, I'll buy them all up Smiley
I'm not closely watching the forums, the numbers that I was quoting are from trades that I observed recently on IRC.

Obviously the boards were also rejected for a reason. Even if you get a few of them to work, I am assuming it's likely that they either throw stales/hardware errors etc. I think the buyer is probably looking for a hobby project more then anything (I know I am not expecting a huge 'win' if I end up buying them, more treating it like a FPGA hobby project).
