Is this still reversible to support blower style coolers?
Yes, you just need to let me know what version you want when ordering.  I'm no longer building the reversible version. |

But doesn't that case work as well? What makes it a worse choice? Only two front fans and USB is in the middle versus on the side. |

...At first I just propped the GPU's up but I have since secured them in place with the Spotswood drop in bracket that fit like a glove.

I think that link you have is for the ATX model but you state that you need to EATX chassis. Will the ATX one work?
Yikes! No, the extra depth of the EATX model is required! |

This is a "drop-in" bracket (requires zero modifications to the case) to mount 7x GPUs and 3x 120mm fans at the front of the deep (25-inch) Rosewill server cases. This latest revision (version 4) supports all of the USB riser PCB widths. Features include: - The frame securely bolts to the sides of the case via existing holes.
- The three fan "cages" included with the case are re-used and bolted to front of the frame.
- There is ~40mm between the fans and the front of the GPUs.
- Space between GPUs is ~15mm.
- The GPUs end up being mounted as low as possible in the case i.e. the bottom of the mounting bracket rests on the floor of the case.
- USB risers (not included) are safely secured to the frame via two bolts (at opposite corners).
- Supports all USB riser boards.
- Ships as a kit (see assembly manual, below). All required fasteners are included.
- Only fits in either of the three Rosewill deep (25-inch) server chassis (note the 'L' in the model numbers):
As of October 2021, the lead time is ~2 business days. $80, plus shipping from Washington state (1-2 fit in a medium size flat rate box). PayPal only.     Latest assembly manual (version 4) |

The R4 is a very strange piece of hardware with the external connections 90-degrees to the airflow.  |

Verified that this'll work with the case on its side.
How did you secured frame inside the case, i don't see any screws. Doesn't it wiggle a bit? good luck with that.. http://www.xtremehardware.com/forum/showthread.php?t=4345480+20+20 bucks, yeah... I've spent almost 500 with tools, time, details, modding, hassle, etc, etc  Installing 300W TDP VGA's it's another thing, that 150W versions. VEGA and 1080Tis will require another kind of designs I''m not sure what you are implying here, but this is just another/different solution to the same problem. |

It's wedged into the case really well, which will make it harder to install for some, so I'm working on a revision to loosen the fit a bit and securing it to one of those holes you can see on the case side. I added a couple of posts to secure the bracket to the sides of the case.  |

@yun9999 asked me to verify that this can be re-configured to have the GPUs mounted at the front of the case.  There is 45mm between the front fan and the GPU.   Verified that this'll work with the case on its side.  |

When I built my open frames, I sourced materials for roughly $80 CAD shipped, per unit.
Definitely takes some time and the proper tools.
Be prepared for metal shavings embedded in your fingers for days.
How far apart are those GPUs spaced?
$300 USD seems a little steep, research or not, there is a limit people are willing to spend.
The GPUs are ~20mm apart. I've been building mining frame for years. Fingers are almost as hard as aluminum at this point. What case is your 8020 subframe designed to go into?
Rosewill EATX server chassis i.e. https://www.amazon.com/gp/product/B0091IZ1ZG/ref=od_aui_detailpages00?ie=UTF8&psc=1 $300 USD seems a little steep, research or not, there is a limit people are willing to spend.
Exactly, ROI is the most important thing in this business. Why should i spend 300$ for a case if i can get nice, solid and fully stackable open frame for under 50$? The idea for a full-blown GPU server case has been abandoned. Now focusing on the less expensive "drop-in"" frame. |

I didn't model the cage that goes around the fan. The three fan "cages" are attached to the front beams. The GPU support beam brackets are bolted to the sides of the case using existing holes (near the mid-point of the chassis). I should have real pics tomorrow.  |

Two more improvements. - The GPU support beam now attaches to the sides of the case.
- The front fans are support by two beams (and posts). The beams are two pieces allowing the fans and bracket to be inserted into the case and then expanded for a tight fit.

Where is the FAN mounted? Behind the GPUs? How are these rails attach to the case? Do we still need to drill holes thru the case to mount them? The place where riser rest on, is it flat for resting riser or is there holes where you can mount the riser on to it to secure the GPU even more so you can do vertical stacking of these 4U server vs just horizontal racking?
P.S Yes you can buy the Rosewill 4U and do the mod yourself for cheaper.............however, it's a lot more tedious work and won't be as good as this solution. This solution will cut your total install time a lot. Very excited about this and hope to get even more detail info. When is this available for shipping and is it possible to put the FAN mount where the GPU front is mounted? This way it can pull the GPU heat straight out regardless of regular style GPU or front blowing reference style design.
The chassis front intake fans are attached directly to the extrusions (in the model, the two horizontal beams at the tail-end of the GPUs). The location of the beam that the GPU mounting brackets are attached to can be positioned anywhere along the depth of the chassis. So if your GPUs aren't too long, there will be enough room to re-position the row of middle fans that are included with the chassis. Note also that the GPUs could be mounted with the brackets at the front of the case i.e. rotate the GPUs 90-degrees. The bracket is wedged-in into the chassis, so permanently securing it to the chassis won't be absolutely necessary. The risers should be loosely attached to the extrusions (otherwise the insulation material might be punctured) via the supplied nuts that will go into the slotted extrusion, which should allow the chassis to be rotated onto its side. Small quantities will be ready to ship next week. |

Here's the final design for the GPU drop-in mount. It supports the GPUs and front intake fans of a deep Rosewill server chassis. $50, plus shipping from New Hampshire. Discounts of 10% and 15% for orders of 2x or 5x+, respectively. I'll start a new thread in the marketplace soon. EDIT: Already had to make a revisions to the design:   |

@Spotswood
Got any picture how the drop-in frame would look like?

This is a classic pic of a GPU bitcoin mining farm that used my mining trays (before asics).  |
