The current/on going reduction in bitcoin price had me thinking this weekend about our vendors.  Remember the good old days of Bitmain pricing merchandise in bitcoin instead of USD?  Yes there are wild fluctuations in btc price, but if the vendors don't think enough about it to use it as value instead of basing products on USD, why should anyone else? Just something to think about.

it is difficult to price item in something this volatile, but great for transmission. In any case, I don't know what they and coinbase are basing the price of BTC off right now? OKCoin?, btce?

Bitmain's website is currently about $8/btc lower than Coinbase.

i see roughly the same price on bitmain (267.23) as on coinbase website ~267-268 and on btc-e/okcoin

Agreed.  You have to watch it though because most of the time Coinbase is higher than Btc-e.  As whacked as the market is right now, it's anybody's guess. Just be sure to purchase when they are close or btc-e happens to be higher if you use Coinbase.

At least during these volatile times, that some of use may want to hold on to our coin, they are offering a way to buy direct via credit card now. Although, I don't understand why they are limiting customers to only 2? You can buy 2 units shipped direct to the US for $779.

replacing the stock fan with a single Noctua ($24.5 on Amazon) makes it much less loud and changes the metallic banging sound of the stock fan to whooosh, although temperatures rise to ~60C and you have to hash at 325 mhz(1075 GH). I am waiting for a second fan to add pull and go back to 350mhz or even higher.

Thanks for the suggestion, but It's now summer here and mine would fry with that weak a fan (it was 41 degrees C here a couple of days ago).  I happen to have quite a few noctua fans in use for other hardware and some spares. While you can design better fans there is still a certain amount of airflow and air pressure you need to generate and this fan wouldn't cut it.

Oh, OK, the temp in my "mining" room is 30-31c and it is an improved 3000 PWM, not typical 2000PWM model; it provides ~171 110 CFM.
I will post here once I add cheap deltas for the pull (klondike_bar suggested putting the scotch tape around the top to make a "shroud", which might help cooling).
Anyway, I just wanted to see if I can host more with extra/new fans (with the default fan I simply can't).

how much value of the S5 coupon ?
If don't mind please send me one coupon, id digitizing

S5 coupons are presently valued at $30.

Mine are showing $40.

If only they could buy parts and pay employees and vendors with Bitcoin. The problem is the world still works and compares to fiat.

I bought Batch 2.

My 2 S5 coupons are for $60. I just ordered my first 2 last week. They probably wont be shipped til next week sometime. If I were to order one now with discount and coupon, its showing 1.202btc after shipping to US.

Bitmain, why are the coupons different amounts to different people?

The NF-F12-iPPC-3000-PWM is actually only 186m³/h which is 110CFM, good static pressure though.

The NF-A14 industrialPPC-3000 PWM (140mm version) is closer with 269m³/h which is about 160CFM

I almost bought some when I was testing fans for the SP20 but 110CFM wasn't much better than the Scythe 1900rpm

I believe my coupons are more because I just ordered 2 at regular price friday jan 2. They then added discount only a few days later.

I have considered maybe getting one more, but I don't think I need 2 more yet so I have one $60 coupon up for grabs. Anyone want it for 0.07btc?

Its to do with the batches and inter-batches having different prices and shipping dates.

You are right , ~110 cfm, I had it incorrect. Nevertheless, it is enough at least for 325mhz/1070GH in a fairly warm room (30-31C)

Anyone want it for 0.07btc?

yep. pm me your address and i will transfer funds tomorrow (going to sleep right now)

Bitmain, why are the coupons different amounts to different people?

Its to do with the batches and inter-batches having different prices and shipping dates.

You sure about that?  Mine was first batch and only $30 coupons.

I'm guessing the logic is that earlier batches got their machines earlier and thus have recouped more of the cost through mining... is that right?

  sell one, then get it again...this is well known...
