Going the opposite direction from OMGWHATISTHATTHING

Okay, so with crypto across the board going up in value, I was keeping an eye on CoinWarz yesterday and shaking my head that my rig could’ve been pulling the USD equivalent of $15+ a day. Even with a dip back down today, I really can’t keep missing days. I built this rig because I was promised being able to run it on free power for 5 days a week, but that fell through so instead I’m drowning in negative ROI.
So I called a colocation place today.
They didn’t know what a crypto miner was, so that’s not a great sign. But they said they’d talk it over with their partner and get back to me. My question is, and I’ll take pictures of it again here in a few minutes, what do I need in order to make a milk crate rig look less like a deathtrap to people? Any ideas?
I already know I’m going to have to get smarter on the power cable management going from the cards to the power supply, and probably find a fan to fit the exact footprint instead of the standalone vornado I’m running now.
Also, so that I have ssh access, what do I need to ask them for in order to reach it? Am I going to have to set up something from dyndns in order to login to it, because I couldn’t figure that out even when I was in the same room with the machine, much less when I may not have any physical access to it.
Alright, thoughts?

Nevermind, new problem.
So my rig was just shutting off so I’d start it back up and the fans would pick up like cgminer was starting and then die again.
A friend had a power supply checker on him and we plugged it into it and everything was green except for -5v and he said it’s supposed to be green across the board.
So I unplugged everything off of it and left one card on one riser and the keyboard and mouse. I’m able to move the mouse for a few seconds before it completely freezes.
Disassembled it completely now and inspecting the board. No damage to speak of, going to try one of the cards directly on the board. Anything else I should be looking for?
Okay, working with one card and mining apparently.

Okay, have been slowly putting cards in one at a time and testing them, and found this:

Dammit. Off to buy another one. Parts of the riser worth anything to anyone?

You might want to look into doing some optimizations like I did with my cards. Once i had hit my ROI I really wanted to drop my electricity bill, since then I have increased my power efficiency by ~30% and decreased temps over 10c on each card.

You might also wanna consider powered risers mod. Think what kinda power the gpu sucks out of your pci-e connection. Ive burned several mobos due to this…
Remeber the pci-e power reserve is REALLY small, and there is no safety with it.
Meaning your copper wires in the pcb of the mobo burns up (done it to four mobos)No problem after following nutnuts powered riser guide

[/quote]Here’s the problem, though. That WAS a powered riser. So what happened?

Looks like the it’s just the track peeling from the fibreboard. That said if it was heat damage I bet it’s because the wires back to the board weren’t cut.
Some people don’t think it’s wise to cut them (as in my guide) but I have 20 cards all running trouble free. Speaks for itself really…

[/quote]Like nutnut said, if your gonna do powered risers. Do indeed cut the wires back to the board.
Never had any troubles with the risers i made after following nut´s guide
