still sorting some "edge cases" for bonuses and refunds but i believe services have been contacted to make it a verified token shortly. It's verified on coinmarketcap at least so the rest should follow, i guess

Try hooking each card to a monitor. I had some strange crap happen with one of my rigs and I ended up using HDMI dummy plugs, like the old HD5850 days, and this got my system to boot with all cards installed. Just throwing it out there.

Okay, I'm confused...

It sounds like something isn't connected right. Might want to pull everything and start from scratch. Plug MB 24pin header in, plug CPU 4pin power in, connect ONLY ONE VGA card to the MB via the riser into the 16x slot and boot. If you get POST go to BIOS and ensure that the settings on the motherboard BIOS are correct and conducive to 6 GPU mining (PCIe to gen1 on all slots is the biggie, and disable onboard VGA if it's on). If Windows is already installed, boot into safe mode and uninstall and wipe all VGA drivers (there's a program floating around somewhere that does this nicely. Perhaps someone else can suggest, I can't recall the name at the moment). Reboot, install whatever VGA driver you're going to use. Ensure card works with new driver. Run miner to make sure miner correctly sees and works with the card.

If all is well, add 1 CARD AT A TIME, configure, run miner, make sure it works.

Once you get beyond 4 cards, Windows gets a little funky about recognizing all the cards. There's a hack around here to fix the registry so that Windows recognizes all 6 cards. Again, since I'm at work, I don't have it in front of me, but it should be relatively easy to find with a brief search.

Also, did you get all these cards new? If not, do you know if any of the BIOS have been modified? If they have, and you're using driver version 16.12.2 or later, any cards with modded BIOS will fail checksum and will not initialize. You'll need to patch the driver to make it work.

Again, though. First step is to tear it all apart and start over, step by step. Don't throw it all together at once and hope it works. Also, DO NOT daisy chain the risers nor the PCIe power connectors. Especially if you have a power supply with multiple 12v rails. Bad things will happen.

Do you have the 8-pin CPU power from the PSU plugged in the motherboard and do you have the two 4-pin molex PCI-E power connectors plugged in as well?

You may be exceeding the wattage your PSU can provide since you're possibly pulling 1200 or more watts at the wall if you have aftermarket 580s that can pull 175 watts each.  In any case, have you installed all the motherboard drivers as well as AMD GPU drivers? Are you using powered risers? basically you need to give us 100% of your hardware and software information in order for us to be of much help.

does it boot with just one gpu?
kinda sounds like a power supply problem but i wouldnt think it would be since it 1200watts but then again it is a thermaltake

Last time this happened they were being DDOSed, maybe they are again being hit with some kinda DDOS attack?

In order to harvest you need a vested balance of at least 10,000. There is no real way to calculate profit because harvesting is sort of a luck game and it is based on your wallet importance level. Some blocks harvested will have fees included, which you get to keep. Other will have a zero balance. I have about 25k vested balance right now and have been harvesting for about a week and have only harvested two blocks. One had a little over 17 XEM and the other had zero.
