Thor Zone Mjolnir: Retainer for ASUS Prime Radeon RX 9070 OC Edition

Transporting your case with such a big graphics card may be dangerous. With that part, you can safely retain it. Also, without it it likely won't stay straight:

Instructions

1. The small standoffs for the riser cable must be raised a little bit, since it will put force onto the back side of the graphics card. It also reduces the risk of the riser cable touching the CPU mounting backplate. You need 2 x ThorZoneMjolnir_RiserCableStandoffRaisers.3mf: 
   
   

   
    

2. For this retainer, you will need to remove one bracket of the original 2.5 inch HDD/SSD holder, as these two holes are used to mount the retainer. Use two M3 x 6 mm (thread length) cylinder head bolts.
    

3. Then, you can mount the graphics card using its three retainer threads using three M3 x 20 mm (thread length) cylinder head bolts.

Riser Cables

As a general rule, you should protect your riser cable with some tape where it is bent and touches the sharp edged case/mainboard (e.g. cotton tape, Tesa 51608):

The riser cable I used is a “Linkup (AVA5) ITX Dual Reverse Socket (v3)” with 18 cm. It fits and offers PCIe 5.0, but I think 17.5 cm would be better, since it is a little bit longer than the original cable. 17 cm may be too short, but I didn't find this length.

Crimping of the PCIe cables

You likely want to shorten your PCIe cables from your modular PSU. I always use Seasonic, at least for this PSU beware: Cut the cable from the PCIe side, not from the PSU side (= leave the plug for the PSU side on). The PSU side has daisy chained terminals (two wires into one terminal, see “8P-5”), it is awful to crimp them:

Warning

The graphics card will fit, but you will likely scratch it a little bit once you put the frame into the outer shell of the Thor Zone Mjolnir.

I used PETG-CF filament.
