I remember reading that somewhere too. I don't know what boards they're talking about but I haven't come across that issue yet and I've used several different boards now, all brand new.

Funny story, a good client of mine comes in to the shop today and needs some RAM for a system. He ordered RAM but it didn't work. I look up his RAM and it's unbuffered DDR2 for a XW4400 workstation. I don't have a XW4400 but I have it's big brother the XW4600 (just the mainboard). So I make a deal with him, I give him the 4 2GB modules from my soon to be miner board and I get nice workstation quality RAM for my miner.
I also have a WYSE Rx0L (3 of them) that have 2 SATA ports and a 4X PCI-E slot. As a test (when I have time) I am going to test a riser card with power to see if it works. The one thing that I am not sure about is wiring the PSU so it turns on with the system and off with it so I don't have a melty mess if something goes wrong. If I understand properly, if I connect the PSU's ground connection to a ground on the thin client to he green sense wire, then when the circuit turns on for the thin client, the PSU turns on. This thin client is very low wattage and could run a card with only 30W or less of overhead. Perfect for cards that won't play nice in groups.

I don't know if thin client work stations are any different but usually the green wire is a simple pull-to-ground to turn it on. So you just need to make sure the supplies have a common ground then join the green wires together. The only problem with that method, and something to be aware of, is that the green wire on some PSUs will leak to ground when powered down, which may be enough to cause the other supply to power back up.

I have never tried but last week a customer asked me to build him a ethereum mining rig. He bought all the parts. 6 1070 cards mining rig.
Well it was a fun build and I have it all stable with windows 10 (his choice) and now I am going to configure the mining for him. I charge $500 labor for the build and configuring.
What is your opinion? Is he too late in the game to mine ethereum? I may build a couple and try it out.

It really depends on his expectations. If he thinks he can run a command and watch $720 worth of coin roll into his account every month, then yes he is too late. It depends on the price for Ethereum, which hit a peak about a month ago. Now it's been trending down. BUT, I think the long term value of Ethereum and the other major coins will be very good. I don't think this technology is a fad, just like the Internet wasn't a fad in 1995.
Also, there are some changes coming to Ethereum. I'm too new to this to be able to explain them, but they're coming. Apparently the difficulty is expected to surge. Also, I think GPUs with 3GB of RAM or less will soon be left out. Again, take everything I say with a grain of salt.... I've only been into this about a month myself
There are lots of coins that are profitable to mine, but it changes daily. So far I've only run Nicehash and let it pick for me. I could probably do better mining coins directly but I've got a lot to learn.

The problem with ethereum is it's volatility and design it is asic proof but take huge amounts of ram/vram it will increase 1 gb every year also depends on hydro rates as the rates here is crazy so much so people are spending 30% of income on hydro.

How much is that per kWh?

.25/kwh 40% of it is now covered by provincial subsides summer 2017.
In 2016 my avg hydro bill was $750 month.

The 1070 cards should be reasonably profitable at that electricity rate:

Excuse my stupid question but if he has 6 1070 he should be bringing in 112 x 6 each month? 672 a month profit?
About that. It's difficult to be sure because of price/profitability fluctuations. Optimistically speaking, could be more. Pessimistically/realistically speaking, could be as low as half that amount some months.

I've noticed a bit of a slight drop of rates at Nicehash, but that's to be expected. I took my rig down for about 30-45 minutes today to change the PSU, put my new 1000W in, got it back up and running just in time for shop close time, Wednesday I continue building new rack. The new risers I got are working well, can't wait for my final RX 480 to arrive.
If I had the money I would be tempted to buy 4X RX 550 4GB cards, they are on at Amazon for $159 CDN each, by themselves they are not a great card per say, but 4 in a system sharing a system load would break even in a few months. But that is another $700~ish which I just can't do at the moment.
My nylon standoffs arrived from Amazon, at first I though the washers were to thick to go in the aluminium extrusion I have and I was thinning it out with a knife, but then realized it will fit with some finesse. I now have two working risers that are mounted on nylon standoffs to an aluminium base. Nice and sturdy. Once the new frame is ready they will all mount on two aluminium bars which will hold the gpu's, then another bar to hold the lip or edge of the PCI-E I/O bracket since OpenBeam is too wide to fit right under the cards and screw them in, but it has a recessed area that the cards can slide into. It's hard to explain, but hopefully Wednesday I can provide more photos.
I am hoping my new 1000W can handle 2 X RX 480 8GB and 2 X R9 Fury, if not I have one of the cables for linking multiple PSU's together, so I an boost it to 1600W with an extra PSU. If I do that, I will run the HDD from the second PSU to make sure there is some load in case of crash or other issue.
I have lots of older Nvidia cards like a GTX 460 and a 9800GT and 8800GTS etc., most of which Nicehash doesn't support. However, I might put them in one system and see if I can run a miner directly, as if they are running together, it might be worth it.

Sounds similar to what I'm doing, except I bought some small (25mm) right-angled metal brackets to fix the top of the card to one of the aluminium bars via the PCIe fixing hole. I'll post some photos when I get time to work on it some more ...
Just struggling a bit now to get a suitable PSU. I'm building a 4 x 1080Ti rig and any suitable 1200W or above PSUs are sold out in the UK it seems.

You can always get one of the harness that hooks two PSU's as one. Then take two 750's or 850's and tie them together.
I know, thanks. Did that with some earlier rigs we built. I'll go down that route if I have to but I'm trying to keep the rig design as simple and compact as possible. Looks like most suppliers are expecting delivery of a new batch of higher-wattage PSUs in a week or two so I'll probably wait.

I just want to find a card I know can be continiously profitable for ~4-6 months and net a gain over the cost of the card and my card budget is ~$200 and preferably a LP card to make use of a system I got for free. General plan would be mine with it for 4-6 months recover cost of card plus a small bit and sell off system probably for close to the cards cost. If I can get a steady supply of systems it might be a good plan to make tidy little wads of cash for my pocket and experiment with things too.

Right now BTC and all the alt currencies are taking a hit, so profits will be smaller from mining, but it's not drastic yet.
I've calculated after I finish paying for my rig (in roughly one pay cheque) I can make at least 50-100 per week. If all goes well, I can reduce or quit my part time tech job and start my own independent business and have some expense money every week.
At its peak, I was making $100 per week which is down to 80 right now. I calculated as low as $50 per week to ensure I didn't overestimate my weekly income as build for failure.
Those figures don't include one more card which is on the way. So I don't include those numbers but use them as a buffer zone.
I also have lots of physical stock items to sell so I think I will be good.
