I've been posting about this motherboard for a while now. My research project with this board is now complete! I have 8 GPU's running on it; Two via M.2 adapters and 6 via PCI Extenders. Video out to monitor is also routed via the onboard GPU. Here is the original post.
I was able to get 7 NVIDIA cards running via this original rig. I can happily say that I'm running 8 AMD Radeon cards on my second attempt. My guess is that I would have been able to get the 8th card up and running on this original build had I given it more effort. I tried once and a lot of the cards dropped off so I backed out and got it back up and running. I think in my install I nudged a few PCIE extenders and should have just reseat them all and tried again. The M.2 adapters can also be touchy and it sometimes takes several attempts to get them to see the GPU. I sold that rig so cannot try it again.
I liked the motherboard so much and it is at such a good price point I bought another one. I also loaded up on RX550 cards in order to do a "CryptoNight Mining Rig" build.
Motherboard - The ASROck Z270 LGA 1151 - https://www.newegg.com/Product/Product.aspx?Item=N82E16813157746&Tpk=N82E16813157746 Here is why. Six PCIE slots. Two M.2 Slots. This allows a total of 8 GPU's. It also will do onboard video so the GPU does nothing but mine.

Cheapest CPU you can find - https://www.newegg.com/Product/Product.aspx?Item=9SIA1K66RA3156&ignorebbr=1 The box is going to be a GPU miner, not a CPU beast.
PCIE Risers - https://amzn.to/2GcDvBG
Now, the secret sauce. http://amzn.to/2EVMx5j This little jewel will convert your M.2 slot into a PCIE slot. You still need the riser board though. When you populate the M.2 slot it will also consume a SATA connector. Not physically so check your motherboard manual.
Other Small Parts
Power Switch / Reset Switch - http://amzn.to/2riG0zJ
I already have this for the power supply - CRJ 24-Pin ATX Red LED Power On/Off Switch Jumper Bridge Cable, Black Sleeved 22" - http://amzn.to/2Dh9XBA
You can also use this - http://amzn.to/2DglvFd - to link your two power supplies together and they will turn on at the same time.
I enjoy building the frames and did another custom build. I took a lot of time with a tape measure and the gear plus the cable lengths. I wanted to center a motherboard between two power supplies and have two racks of cards. I also wanted it wide enough in case I switched to a B250 board that would run more than 8 GPU's.
I gave it a coat of flat black paint. I took a little extra time with it and covered nail gun holes and wood flaws, sanded, then painted. Some screws are still visible because I couldn't find my counter-sink bit! I also thought I was being cool by using some hickory we had left over from a flooring install. It's so freaking hard of a wood that it was tough to work with! I won't do that again but this rig has some very sturdy cross members! My only oops is I have twice neglected the SSD mount. I don't have a real custom way to mount it. Lastly, I put in a swivel board on each end to hold in the power supply. You will see that in another photo.
I still follow my own advice on Windows 10 Prep.
Read this post, do the steps. I have also learned to install TeamViewer right after Windows Loads. Don't wait!
The lowly AMD Radeon RX 550 with 2Gb of onboard VRAM. Who in their right mind with mine with one of these cards?
I like the RX 550 2Gb card. I personally like the Gigabyte version. They don't require external power and I've found them to have decent VRAM in which to mod the bios and overclock. I've purchased them new anywhere from $95 to $130. The produce around 420 H/s on XMR-Stak and more with aggressive overcloccking.
They also sip the power. Here i have the rig of 8 on a single 750 watt power supply even though I have two power supplies loaded up on the rig. One thing I have also learned is that you don't have to apply power to the 4 pin plug on the M.2 adapter. Powering the riser is enough.
That's the rig.
You can see the while M.2 adapters in there somewhere!
Here is a beautiful picture. 8 GPU's in Device Manager.
Photos or it didn't happen. Above is XMR-Stak detecting the GPU's.
Here are the threads, two each per card.
Another pretty sight.
They are not Vega's. They don't hash like a Vega but they don't cost like a Vega. Not a bad rig. Cost per hash is much lower than many other AMD cards on the market. Do the math for yourself if you are curious. Hit me with questions.
Rachio has just announced version 3 of their popular sprinkler system controller. Rachio's generation 2 hardware was such an improvement on their first controller it may be hard to top. Gen 3 looks great and has new hardware to go with it. First Look video below!
Rachio's approach to irrigation hardware has been pretty straightforward.
Replace your existing irrigation controller, water smarter, take advantage of mobile to control it.
What they have done over the past 2 iterations is make it easier to do all three. Generation 2's hardware simplified the install immensely and the Rachio 3 Smart Sprinkler Controller looks to do the same as well as offering more options for the homeowner. So how do you improve on an already great controller?
Increase the smarts with enhanced weather data
Add a 5Ghz radio along with 2.4Ghz Wi-Fi
Add long range communication for add on devices
Let's just jump to the new devices. Rachio is announcing an add on flow meter called the Rachio Wireless Flow Meter. It will sense water flow and shut down water supply if it detects a leak.
This is an interesting addition to the product because it moves Rachio from a true DIY product to on that may need help from a professional. If you know your sprinkler system you know you have a back flow valve somewhere on your property. It is usually above ground and the Flow Meter can install in-line, after the backflow valve. Rachio has tips and guidance on the install if you would like to attempt it yourself but it may be prudent to involve your irrigation pro if you don't already have the tools to perform this type of work.
The "smarts" surrounding Rachio 3 cannot be overlooked. Their new weather intelligence is impressive. You can gain insight on weather data within a 36 foot radius of the Rachio 3 controller. Thirty Six Feet!
Rachio 3 ships April 2018 and can be pre-ordered today at http://www.rachio.com Rachio Flow ships May 2018. Pre-Sale pricing is $279 for the 8 Zone and Wireless Flow Meter. $329 for the 16 Zone and Wireless Flow Meter. Outdoor enclosures are still $29.

Digging in a little more about what to report and what to tax. This podcast below is a wealth of information for anyone that is holding a coin.
Some items i have heard:
Coinbase provided the IRS the information of anyone in their system with $20k or over in assets.
Deposits to Coinbase via FIAT currency are not taxable events.
Trade of BTC to Altcoin IS A TAXABLE event.

I am finally replaced my custom built desktop PC after about 5 years.
Now that I have a retired computer with a decent pair of video cards I want to dip my toe into cryptocurrency mining. Although I realize the old equipment won't produce as much per watt as newer graphics cards, I already have 2 HD 7870's that will just collect dust if I don't do something with the system. There are also a few older components lying around so I've been contemplating repurposing my old computer and components to create computers for the following roles:
A dedicated storage server that would also host my Plex media server and backup content locally. (Yes a NAS box could do this, but I already have PC parts and don't want to spend $1k+ on a NAS box that can accomodate all of my 4TB and 6TB drives). A cryptocurrency mining rig A router/firewall replacement
I'm new to mining and know that the mining rig needs graphics cards, but how significant of a difference does the CPU make in a mining rig? I can either use an Intel Core i7-3770K or an Intel Core i3-3250. The dilemma is that the i7 should be able to transcode roughly twice the number of simultaneous streams (4) that the i3 can transcode (2+) based on the PassMark scores. I don't want to mine on the same machine as my Plex server since my previous mining attempt created OS stability problems.
Does memory make a large difference in cryptocurrency mining? I can either use 32 GB of ram or 16GB of ram.
Lastly, would it be better to combine the storage/Plex server and router/firewall roles into a single computer and run each as a VM? What do others recommend for this? I've heard about Pfsense and watched a few setup videos, but that appears to be designed to run on a dedicated system.
Thank you in advance to those that have constructive feedback for me.
