A small improvement... The PSUs are now secured to the frame via three mounting points.  |

I solved the issue of the front fan screw heads by simply removing the plastic shroud holding the dust filter in place (the suction of the fans is enough to hold the dust filter in place). I didn’t want to move the fan mount back because I didn’t want to sacrifice cleanrance since I have 1 card that’s over 11” long and I also remounted and kept the center fan wall for extra airflow.
I'm not following this particular point. I have the same bracket and there were no issues as far as closing the front face place; no modifications were necessary at all. I simply moved the frame back enough to where the side beams align with the screw holes in the case side. There's no need to reposition the entire bracket in order to adjust for not being able to close the front door properly. The fan sub-assembly can be secured to the base of the bracket at any position (you should only have to inset the fan sub-assembly just a couple of millimeters).    |

@octominer can you provide the technical specs for how the power on/off circuitry is designed? Apparently it was designed differently than 99% of motherboards out there to where an optoisolated gate is not able to power the board on and off. Thanks
fwiw my onda b250 d8p v1 has the same bug, power button will turn it on but not off. cant see anything in the bios either. sorry for the non helpful reply, just another datapoint. Hey! Our motherboard does actually support turning off from the power switch. Please have a look here to see exactly how to connect the button switches and LEDs to the motherboard. https://youtu.be/49YBnjIHMDc?t=538Odd, how the rig turns on when the PSU is turned on. What type of switch is used on your case i.e. normally open momentary switch, etc.? |

Are these stackable? and price shipped to canada? USPS
They can be assembled in such a way that will make them stackable, just let me know when you place an order. In order to get an accurate quote I would need your postal code, but it seems everything I ship to CA is $45-55 USD. -Rich |

Got mine yesterday. Thank you! I didn't see assembly instructions on your site yet, are they still in the works?
Thanks!
Yikes! No, manual just yet. Assembly is straight forward and a lot like every thing else I make... - Bolt the posts to the three short beams via M3x20mm bolts and washers. - Bolt feet to the bottoms of two of the three sub-assemblies using M3x6mm bolts and hex nuts. - Bolt the long motherboard support beams to the three sub-assemblies via M3x35mm bolts, washers and hex nuts (the ones with the feet go on either side). The rest of the assembly is mostly covered by the current two PSU mining tray http://spotswoodcomputercases.com/wp/?page_id=9137 and the old/original tray: http://spotswoodcomputercases.com/wp/?page_id=9018I should have this manual ready tomorrow night. I apologise for the inconvenience! |

Are these rdy to ship once order? Or is there a wait time?
Lead time for these is ~5 business days. So now you have my zip and PP info. I assume you will email when you require payment for the order? Invoice sent. Thanks! |

Price drop? I paid $110 +tax and shipping on the 25th... Still going to ship this week?
Yeah, I dropped the price because of basically zero interest in these.  I sent all a refund for the price difference. -Rich |

just installed a V4 bracket.
install takes a while, lots of little screws, but fit and finish is great once you get it all in. in my setup i'll have room to put the mid fan wall back in (definitely needed IMO)
criticisms:
-I don't think the front fan screws need to be so long with use with double washers. you could easily just use the short M3x6mm screws (with no washer), and just stick them through the hole in the fan shroud like it is stock. I only didn't do this because i wasn't provided with enough of the small screws to do it as they are needed elsewhere.
-the long/tall screw heads protruding from the front of the case prevents the front dust cover/door from closing all the way.
i realize the OP/designer/maker intended to reverse air flow, but i think this is a mistake. front to back airflow is better for a server case setup.
The front fan assembly can be mounted at any depth i.e. if the door can't be closed you can reposition the fan assembly a bit further into the case. I will note this in the assembly manual. The bracket was designed for the at-home miner, where three fans helping to exhaust heat at the front of the case is a good setup. You can get a version of the bracket where the GPUs are oriented to exhaust toward the back of the case. |

I'll take one. Where do I send the PayPal payment?
Great. I just need your zip/postal code and PayPal email address. PM sent. |

Ya I tried that, but I just saw that they are moving locations and won’t be accepting new orders till mid March.
Old news. We moved last year.  Currently accepting new orders, but the lead time is at around 7-10 business days. -Rich |

Octominer has yet to reply to my request for this information, so could someone who has this board please send me a simple drawing of its mounting hole locations.
Thanks!
Rich
I'll see if I can trace out the mounting holes with measurements. We'll be in the market for a frame if you can make one to fit this motherboard.  I just sent you a pm with a tracing + measurements for the mounting holes. Thank you! Coming soon...   |

Rich,
Any possible update to the tray or additional mod to add a server PSU?
The server PSU mounting bracket is a separate product. |

This bracket is now at its fourth generation. The latest update was made in order to support USB riser boards of various widths. For those that have been watching this bracket evolve, version 4 is a blend of version 2 (USB risers mounted to slotted extrusion) and version 3 (GPUs sit as low as possible in the case).  |
|
|
|
Now that USB risers come in varying widths, I've updated the design to use slotted extrusion for the riser support beams. The slotted extrusion still allows the GPUs to be mounted in the case as low as possible and now at any distance apart.  |
