Hi Guys, I put this in the alt section but not replies so hoping some one here might be able to answer it.

I'm looking at possibly setting up a mining rig for alt coins, I've got some friends who are mining and I've been looking at the new asic miners but have also been doing some figures on what it would cost me to build something now and looking for some feedback on spec's.

As most the mobo's and gpu's recommended are all out of stock I've been pricing up on what I can get via local suppliers and what I've seen in the forums, current list which can change is, (all of the below I can get right now)

ASUS R9290-4GD5 4GB DDR5 PCIE Graphics Card (x2 or x3)
Gigabyte F2A88X-D3H ATX DDR3 FM2+
AMD A4-5300 Dual Core 3.4GHz 2MB Cache Socket FM2 65W
SilverStone Silverstone Strider Plus 1000W Modular ActivePFC ATX 80plus Silver PSU

Do those items sound like a reasonable setup, would 4gb of RAM be enough and how many powered risers should I run with that mobo, or do I need to bother if I only use 2x GPU's? I can get some better mobo's that are also recommended but at over twice the price and from what I've read sounds like the above should be fine but any recommendations are appreciated.

I can run it in our server room at work so its temperature controlled so just planning on a basic case with a few fans which I hope should be plenty to keep them under control.

Let me know if there is a better setup I should be considering otherwise I think its worth the investment as I should be able to get it to
