Mining Chassis

Buy one, or everything you need to roll your own

Last updated: Thursday, March 4, 2021 at 5:02:36 PM

I'm working on a store that can sell the custom acrylic pieces and maybe the 3D printed brackets and feet and caps. There are metal brackets listed below, so the feet, caps, and acrylic pieces are all that are currently missing to DIY one of these. Those are all fairly easy to make by hand, but I should be able to find someone online that is willing to sell these pieces. Working on it now.

Also, read the details. Not all of this is required! There's a lot of optional stuff here, and several things that you probably already have if you've ever built any PCs from components before, such as the fine and course PC screws, fan screws, etc.

Tools


3mm Allen ball-end T-handle driver (for the M5 bolts), optional but nice (an allen key comes with the bolt sets, too):

3 mm Ball End Hex Key with Journeyman T-Handle, 6-Inch Klein Tools JTH6M3BE

6-32 tap in case you want to make your own GPU rests (you can pop the tapered one in a cordless drill and set it on slow and run it through that way):

Irwin Tools 2518-3 Piece Set - 6-32 NC, High Carbon Steel Machine Screw Tap

Essentials


If you want to order metal corner brackets you only need 16, but these will work. Note that these t-nuts and bolts are the slide-in type. I believe the M5 bolts and quarter-turn t-nuts will work with these and will verify that soon and update this listing.

PZRT 2020 Series Aluminum Profile Connector Set, 20pcs Corner Bracket,40pcs M5 x 10mm T-Slot Nuts, 40pcs M5x10mm Hex Socket Cap Screw Bolt for 6mm Slot Aluminum Profile Accessories

These are the "long" bolts for use with the flat brackets and GPU rests:

M5-0.8 x 10mm Button Head Socket Cap Screws (M3 to M10 Available) 100 PCS, Stainless Steel 304 (18-8), Full Thread, Machine Thread, Bright Finish

The "short" bolts for the PSU mount (both), the motherboard, fan mounts, riser tie-downs, etc:

Quarter turn t-nuts are the thing that makes this MUCH easier to build and maintain as they don't require any disassembly of the t-slot to slide the t-nut in. They simply drop in place and turn and lock:

6-32 screws, also known as "coarse", for PC building (these go into the threaded holds on the GPU rest as well as usually are the right screw for mounting an ATX power supply:

You could also probably go with something like this for the 6-32 screws and skip the tapping step on the GPU rests:

Rounded Head Thread-Cutting Screws for Metal

M3-5mm screws (aka "fine" screws) for mounting the motherboard to the standoffs:

HONBAY 100PCS M3x5 Black Zinc Round Head PC Mounting Computer Screws Computer Case Fixed Motherboard Screw

M3x10mm standoffs for mounting the motherboard to the acrylic motherboard tray (these require M3 nuts, below):

ZXHAO M3 Male to Female Thread Brass Hex Standoff Pillar Spacer Hex Spacer Nut (M3 x10+6mm) 100pcs

M3 nut to hold the standoff on the motherboard tray:

Shapenty 100PCS 3mm Small Stainless Steel Female Thread Hex Screw Nut Fastener Tool, M3

14 inch zip-ties (only needed for attaching HP PSUs to the HP PSU tray:

Cable Zip Nylon Heavy Duty Self Locking Wire Ties (14 Inch, Black)

Fan screws (you need two screws per fan to mount these using the acrylic fan mounts):

Honbay 100PCS M5x10 Black Zinc Computer Case Fan Screws Computer Cooling Fan Mount Screws Self-Tapping Screws

To build your own chassis, here is a link to the cheapest way I've found to get the extrusions, and the bonus is that it's all pre-cut for you. Here iss a link to a shopping cart in black 20mm t-slot. Note that the black is about twice the price of silver, so buyer beware. If you really want to cut your own, I've used this t-slot to build a chassis:

Recommended Computer Parts


Fan for open chassis mining:

Delta AFB1212SHE-PWM 120mm x 38mm 4pin PWM+Tac Sensor Extreme Hi-speed 3700 RPM 151 CFM Case Fan

Riser (definitely works with my riser tie-down):

FebSmart PCI-E Riser for Bitcoin-Litecoin-ETH Coin PCIe VER006C 6 PIN 16x to 1x Powered Riser Adapter Card 6-Pin PCI-E to SATA Power Cable-GPU Riser Adapter-Ethereum Mining ETH (6 PCS)

Mining motherboard:

ASRock H110 Pro BTC+ 13GPU Mining Motherboard Cryptocurrency

CPU for above motherboard:

Intel BX80677G3930 7th Gen Celeron Desktop Processors

RAM for above motherboard/CPU (you really only need one of these for mining):

Patriot Signature Premium DDR4 4GB (1x4GB) 2666MHz (PC4-21300) UDIMM with Heatshield PSP44G266681H1

USB stick for mining operating system:

Micro Center SuperSpeed 5 Pack 64GB USB 3.0 Flash Drive Gum Size Memory Stick Thumb Drive Data Storage Jump Drive (64G 5-Pack)

ATX power supply (will run a motherboard and FOUR GPUs but may not have room then for riser power):

EVGA 850 Bq, 80+ Bronze 850W, Semi Modular, 5 Year Warranty, Includes Free Power On Self Tester, Power Supply 110-BQ-0850-V1

Adapter cable to run a GPU on the CPU2 output of the above PSU:

(CPU to GPU) CPU 8 Pin Female to Dual PCIe 2X 8 Pin (6+2) Male Power Adapter Splitter Cable for Graphics Card BTC Miner 9-inch (23cm) (Pack of 2) COMeap

HP PSU:

HP Common Slot Platinum 1200-Watt Power Supply Kit 656364-B21

Instead of the above HP, though, I recommend buying this kit from Parallel Miner. To run 8 GPUs in one rig, I would buy it with 16 cables and the 16 port breakout board. Then run 4 GPUs from the ATX PSU with the CPU/GPU adapter cable I reference above, and then run 4 GPUs and all 8 risers using the HP. I'm doing this on three rigs and it works wonderfully with no need for any additional power splitters. This also avoids using any of the SATA power connections, which are often of sketchy quality when it comes to trying to use for "high current" applications like this. Even risers shouldn't be powered by SATA power connections. There are many examples of people who have never had a problem, but enough examples of people who HAVE had problems that I like to avoid those if at all possible. Using four pin molex is a better option than SATA, but I like to avoid that, too. In my rigs the only four pin molex connections are the ones required to go to the motherboard.

Optional Items


Way more Fiber Grip than you'd ever need to assemble one chassis (see the installation video for how to use this…it's not required, but it makes working on these chassis a lot easier as it makes sure the t-nut will actually turn back and forth under the acrylic for you):

Finish Line Fiber Grip Carbon Fiber Bicycle Assembly Gel

If you want to get fancy, here are some pretty nice looking thumb screws that will work great for attaching the GPUs (and even the PSU, I'd guess):

Powlankou 20 Pieces 6-32 Computer Case Screws, Anodized Aluminum Thumbscrews, Fully Threaded Knurled Thumbscrews, Thumb Screws (Black)

Fan grills (optional, but if you get really good fans, these might save you some flesh):

SamIdea 120mm Diameter Silver Fan Finger Grill Guard Protector with Screws (Pack of 6)
