Re: Octominer B8PLUS 8 PCIe Slot Mining Board (Motherboard, integrated CPU)
I've got two of these running WIN now, one a cryptonight rig with 8 MSI RX550 I was really nervous that the board wouldn't be able to handle the start up power but with bios mods it's sailing along. The other with 8 Galax 1050 TI the 1050 TI rig runs with the Octominer ATX power supply.
Both builds took under 15min including unboxing etc which is epic.
RX550 rig is getting stable 3960 H/s @ 411W at the wall from a coolermaster V850 and the cards are running ridiculously cool around 52-5 C which is only 20 or so C above ambient on a regular day here..
1050 TI is doing 4Mh/s Neoscrypt / 121Mh/s Eth @ 624W at the wall from Octominer's PSU with cards running nice and cool around 67-9 C which given the ambient temps here is brilliant.
I haven't done anything sexy just used rubber kids playmats, dumped them on tables and built the rigs right to the edge of that. The playmats are exactly the right thickness for two slot GPUS to support themselves on the table underneath with close to 0 droop. Ventilation from my rig room is just two overpowered stand fans sucking air out the window and bringing up cool air from downstairs.
This beats the everliving crap out of building junk/dinosaur rigs which I've been doing for ages.

That's great! Thanks for the feedback.
In general how's your experience with the Octominer motherboards compared to your previous rigs ?
They're more expensive in terms of outlay however, 15min 8 GPU builds including getting WIN/Ubuntu installs started there is an enormous saving on time. I've been buying used 2-4 slot complete machines and used everything from duct tape, to bailing wire, to hacksaw case mods to put them together and it's just not worth it.
The math works like this:
75$ For a used 2 slot PC with the works including a 500W PSU.
12$ For a decent riser and 1 or 2 molex - pcie converters.
2$ For a bamboo dish rack that holds up to 4 GPUs.
89$ Total.
So 356$ for the equivalent of an Octominer going by number of slots.
555$ For "Complete" Octominer set up 8Gb Ram 120Gb M2 1650W Atx.
Sure, it's roughly a 200$ price difference, however it's 3 less installs to do, it takes up a lot less space etc. You don't have to hacksaw and drill a crappy case to add a fan to it etc.
Yes, you can run scripts etc if everything is linux and if I were doing this full time I would be. However, at my hobby level with the Mrs running things when I'm not here, this makes an awful lot of sense and raises the pleasure level significantly.
THIS^^
The amount of time saved from the builds with the octominer case is huge. I bought 18 complete setups recently and I can tell you that going from the open rig concept with risers (PITA) to the octominer setup made things so much easier. Also I'm going more dense in my setup and needed a better way to control the air flow in my shed (12 X 16 X 8H with barntop). I have 450A service being installed this weekend and 42 Avalon 741's to setup along with 20 Avalon 841's.
Anyways thanks octominer for your great product and service. I'll be posting photos of the completed setup once its all said and done.

Hey Tim!
