Updated: Version 2 of the 120AIO for OneSlot & TwoSlot Beds, made stronger but with a more traditional fixing. Added a 240AIO version that could also hold a 360AIO and is as thick as a typical fan (25mm) for strength, so you will need to use radiator screws to fix to it.
...
This single print, test bed frame will house a standard PSU inside and has posts with 2.6mm screw holes for the MATX motherboard to fix directly to it.
You will require a 3D printer that can print 235.2mm high.
- Type 01 is the bare bones cage.
- Type 02 has a side area good for tidying some cables but I made it as a place to store your usb or sata 2.5" drive.
- Type 03 introduces a side slot that can take add-ons like a gpu/expansion slot bracket, an AIO radiator or even a holder for a DVD drive or 3.5" HDD.
- Type 04 has an additional slot at the other side (MATX max 205mm wide) for more add-ons like a bracket to help hold a long GFX card or a cover to that goes over the top of the motherboard like a lid.
- Addon_ExpSlot is to help with somewhere to anchor your graphics card to.
- Addon_120AIO is to screw a 120mm sized fan or AIO to if it doesn't stray too far away from the 120mm dimensions.
- Addon_TwoSlot_120AIO is a more robust 120mm AIO attachment point requiring the Type04: Two Slot test bed.
I made this so I could build a SteamOS box with the power of a steamdeck. Its specs are : Ryzen 3400G, MSI B450M, 32gb 3200CL16, 250gb NVME & an EVGA 450W PSU and I am surprised by how capable it is in Bazzite (Linux Steam OS-like distro). That is with one big caveat: Steamdeck level settings, so new heavy hitting games will need some serious tweaking (like everything on low) and 720p@30fps, but older games do 1080p@60fps with no issues at all.
My old Noctua NH-D15 is really overkill on that 3400G and the Wraith I got with it would have been fine but I just had to do it.
I'm gonna break my rusty cage and run...
