They do not sell the motherboard by itself but do sell a barebones server for 5,195 USA.
Prices do not include tariff, VAT or shipping and payment is expected at time of order using wire transfer.

Servers are assembled by request, so you can order it with any cards you wish.

That is just...insane. I'm sure someone will certainly find a use for it, and I'm sure someone on here will inevitably get one. Would certainly allow you to run through those shares.

Like what I had to say? Send me some Bitcoins!

I doubt...

завидуй молча и сперва добейся
envy in silence and prove that you can do it better

8*6990 would have been godly for mining

It will give 5.1 * 8 TFlops = 40.8 TFlops, 5,28 GHash/s
the whole network is 580 GHash/s - bitcoincharts.com

10 500 000 BTC per 4 years = ~7200 BTC/Day

7200 * 5,28/586 = 64 BTC / day

~220 days to cover costs (without electricity)

If only this can work without overheating in first couple of minutes, it would be ~4.32 GH/s. (8 x 5970)
~55.7074180016 BTC per day at next difficulty (after tomorrow).
Let's assume that difficulty will increase by 30% every 10 days for easy counting.
557 + 340 + 273 = 1170 BTC first month
190 + 133 + 94 = 417 BTC first month
66 + 46 + 32 = 144 BTC third month.
8 * 300 = 2.4 kW just for the cards * 24 * 30.5 * $0.1 = $175 per month for power, oops, we are not profitable already.

I did a computation like this and in my country it won't be profitable in around 30 days.

You are assuming that the bitcoin value will stay the same.
I actually still think it will raise until some certain point, so it may be profitable.

220 days to recover costs of a dual xeon 6 core system is really not bad.... but I never meant it would be profitable for mining, I wanted to say it would be crazy for mining as in it would produce alot of hash/s in a single system

Behind the cobwebs in your mind.  You necroed a 2.5 year old thread?  How do people even find these threads?

Way too much heat.

I had enough problems with 2 7950's.

8 cards would not have enough airflow, and would melt, unless you were pushing some serious air with some burly fans.
