Any word on my 0% fee? Right now I'm still mining @3%...

@87

Sure thing... but it has suffered a bit of modification as the video card supplier just run out of those... I've just bought 2 pieces of R9 280X... should be here tomorrow or the day after the most... I'll buy another 2 as they come up... somewhere

At the moment only the PSU has arrived... some 4 hours ago

As a riser cable you should use 1x to 16x PCIe extenders/risers... as I understand they should work for all slots on your MB. But if you have the possibility you should buy the extenders for your specific ports. In your case 3 pcs. of 16x to 16x and the rest 1x to 16x (2 pcs. in your case).

I'm also building one 
Here are my specs:
Gigabyte Z87X-OC with Intel® PentiumTM G3220 and Kingston 8GB 1600MHz DDR3 Non-ECC CL9 DIMM (2x4) as a base.
As hashing units I am expecting 4 MSI AMD Radeon HD 7950, 3072MB, GDDR5, 384bit to be delivered as we speak.
All this will be powered by one Sirtec - High Power PLUS GOLD 1200W - arrives on Monday... I hope.

I actually opted for this MB because I have no way to easily procure riser cables... from China they will arrive somewhere from 9 all the way to 29 of Januarry 

Have phun 

I just found this website (http://bitcoinrigs.org/) and I wonder: is this a scam?
I would really like to buy some HW from them
