Do you have any image?

nope, but it's not that hard,

I did something like this:

1) download Debian Wheezy rasbperryPi image from here: http://www.raspberrypi.org/downloads/
2) write it to SD card: http://www.raspberrypi.org/documentation/installation/installing-images/README.md
3) connect microusb for power and monitor and keyboard to rasbPi and boot up, there will be little setup, i think you should do the 1st step atleast (just choose to enlarge partition, and all will be automatic)
4) connect fash-hast card to raspbery, after that when typing 'lsusb' you should see a new device that was not there before you connected fash-hast card.
5) install some more packages:
sudo apt-get install build-essential autoconf automake libtool pkg-config libcurl3-dev libudev-dev
6) clone cgminer from git
git clone git://github.com/ckolivas/cgminer.git
7) compile
cd cgminer
./autogen
./configure --enable-hashfast
make
Wink

run cgminer as usual

EDIT: And don't forget to tip ckolivas

How are the miners performing?

at least 13% under the promised 750gh/s spec. over 30% under spec in my case.

Ken, I would like to get refund now, its been several times i'm asking for it.

Order AGWQBVSDM /2013-12-03 / $769.00 / Bank Wire

I'd like to buy with BTC but had no joy, not brilliant communications

Still no answer.

Did you already try this?

Sent an email asking to pay in btc.

Yes, we take BTC,

Order and select wire transfer and in the comment put that you want to pay with bitcoins. We will then send you a bitcoin address and the amount of bitcoins to pay.

I recall Ken actually sent a pre-configured RPI to a customer who was having trouble, so at least one person is using an RPI, but I suspect there are others. I think VinceSamois is using one, but I'm not sure.

So I've got 3 of these on the way (hopefully), going to try an open loop watercooling setup on these which should outperform any closed loop watercooling i.e. H80 / H100

I'm interested in what kind of open loop system you're planning? I was looking at doing some absolute benchmarking open loop just using the city water supply, but that's really not viable for anything other than short term stress testing. I've often thought it would be a great use of lake/riverside property, but I definitely don't have any of that.
If you could make it work though, evaporative cooling would be a cool project.

If you want to see how many cores are still active after awhile, turn on debugging in cgminer and look for the inflight value in the OP_GWQ_STATUS message.

Thanks, I was wondering how I can see that

Also good to know about those core counts and max theoretical hash speed (y)

got my toy today, installed it into mini-itx case (pics tomorrow), cooling with corsair H100i

borad had a label: Passed; 707GHz, 0.88V, 800MHz

after 25 min
image removed
and
image removed
started mining on eligius

http://eligius.st/~wizkid057/newstats/userstats.php/17tPccT1jgghUMK7J9XThXtXZkGERQSFeS

EDIT: it's running on win7 in virtualbox on a mac

Assuming you mean 707GH/s, that is impossible with 800MHz. The chip can only do 768 hashes per clock on an absolutely perfect chip even without factoring in any losses due to HW errors, rejects, work restarts, etc. At 800MHz your theoretical max is about 614GH/s though you could go above that (especially briefly) due to variance at high difficulties.

If you want to see how many cores are still active after awhile, turn on debugging in cgminer and look for the inflight value in the OP_GWQ_STATUS message.

this looks like a good deal but i have been screwed before buying off of a self moderated thread. do you take escrow?

My Cgminer keeps shutting down with the error" LIBSUM_ERROR_PIPE" which is apparently error you get when the software sends a command that the hardware is not capable of. At least as far as I google it.
Ended up installing CGWatcher to restart the miner when it locks up. Seems to be working better now.
Anyone else with similar error?

I noticed, that when starting cgminer, hashrate looks really desireable.. but then those messages pop up:

NOTICE: Hash Core Error: Squelching die 0 core 80
etc..

after a while when al lot of cores are "Squelched" hashrate stables to that what is seen on pool about 480G Sad

I'd really like to know how was it tested 707G as the label said inside the box...

I'll try to improve cooling in few days, see if that helps..

Indeed, in fact they report less than half the hash rate reported by cgminer.......try a different pool, I know eligius have been having a few issues lately........

Nah nothing wrong with eligius, but doesn't hurt to get a second opinion from another pool.

I've played with it about an hour now in the morning. Cant get the same results anymore.. also btcguild reports about 400G.. maybe it's problem of virtualmachine, I'll try to install raspbPi later.

oh.. here are cover-off pics:
