So, after a long time, here's the update:

4 out of 5 riser cables were broken.
Had to get replacement from different merchant.
Replaced one 280x DUAL with 280x TOXIC.
Added a second PSU.
Runs non-stop since a few days.

So that you don't have to stick a fork into your rig every time you have to reset it or power it on, try out these front panel connector button replacements.

They have saved me a ton of effort!

Thanks for the hint, but I changed the BIOS, so when I switch on the PSU, it also starts the computer.

More to come.

We (my son and me) made the first test, installed Win8 and it works fine so far.

I leanred how to switch on a mining rig without a power-switch... feels like short-circuiting a car

.

Next step is a test in a plastic crate... later today.

Thanks for the warning. What do you mean with Molex?

I bought powered risers in case i need them.As the blog says, this is my first rig ever, so I am learning by doing.

About your first question: nothing is built together yet, will happen tomorrow.

I've heard of cheap powered risers catching fire when both the motherboard and riser have Molex plugged into them.

Have you undervolted the GPUs and if so, how many wattage reduction did you see? Also, since the H81 Pro motherboard already come with 2 supplementary Molex for PCI-E, why did you get powered risers?

Today most of my hardware arrived *happy*.

Thanks to all on this forum who helped with their experience and input.

I hope to get the rig running tomorrow and will make a detailed list of my learning.
