    I've lurked here long enough and walked into Micro Center enough to give me the motivation to make my case entirely from scratch after looking at a shelf full of cases but not the one I want.

    The title of this build has no meaning. I gave it the most random name I came up with while sounding Japanese for this post. Like Häagen-Dazs. Sounds Dutch, but has no meaning.

    The materials chosen will be limited to a budget of some sort and my abilities because the costs involved can blow past an estimate of $3000.

    The main gist of this build:
    • Segregate GPU due to heat output compared to other components
    • Includes air filter of some sort with enough airflow instead of a mesh screen
    • Make it float
    • Wireless Qi Charger



    The Build Itself Going Forward.



    I used Fusion 360 to get a sense of what I am working with. I haven't settled on the orientation of the PSU and storage drives. They will be on the right side of the case. A small portion of what I designed in Fusion will be referenced in the build such as the case and placement of components.


    The whole case will use aluminum extrusions as the skeleton of the build. This is what I am starting with. Dimensions are 19" x 26" x 25" (Width x Depth x Height in inches) for the frame. Aluminum extrusions are 1" x 1". The dimension itself is large enough to house 2 computers in one frame. I made it this large to have adequate airflow through air filters I want to use but haven't decided which ones. I do not plan to use mesh-type filters on PCs.

    I'm currently waiting for the corner brackets to come in.

    I got my corner brackets a few weeks ago and did some modifications to make them work with the screws I got from McMaster Carr. I've been working to complete the main structure due to my busy schedule

    What you see in this photo is the main base of my PC. I'm using metal wire rope for this build to implement Tensegrity. This is the first inspiration going into this build. I'm doing this because of the Tensegrity posts from last year. It got me thinking to look into Kenneth Snelson's work to understand it.

    One thing that irked me about the tensegrity structures posted recently was I think they were more like a suspension-based Tensegrity structure where the main and exterior links are flexible and in tension. I do not see what is recognized as a compression element when the links are in tension.

    I plan with this build to utilize Snelson's definition of Tensegrity. A structure holding compressible and tensile members in separation.

    Adding the parts for tensioning the wire rope to the base.

    These are machined blocks for which I will be using to lift my PC after adding a stop to the wire rope in my desired location.

    I was testing the turnbuckle function before proceeding further.





    [​IMG]
    This photo shows I will be using a single aluminum rod in order to lift my PC case above the base. I figured that the property of Tensegrity can be exploited to use this effect. It's very unstable in its current state until I find a way to attach the wire rope to the main base. I can confirm the whole case is being lifted by that single aluminum rod on the base if I held it neutrally in my hand.

    That is going to be a really fancy design :thumb:

    Have you considered to use 3D connectors instead of the brackets?

    love the idea. :D It's too early in the day for my brain to wrap around this. I assume you are missing a support in the Y axis still?
    Also, is there any way to use springs for tensioning so the whole thing can be more "floaty"?

    I did. I choose not to because I wasn't sure how the exterior is going to be such as screw-on metal, wood, or plastic panels, and call it done.

    I wanna say yes, there is a way to use spring for tensioning, but not sure where to add them. It's why I when for block and cable clamps to provide a point for lifting. The clamps on the tensioning wire rope to the center rod aren't necessary. I could drill and tap a hole for a 1/4-20 screw to hold the wire rope in the blocks at that point.


    Y-support? I'm assuming side to side and not the z-axis in the direction of the rod. I'm still working on how to tension it and looking for the pivot point.

    After spending 3 days and fiddling with the wire rope, clamps, and using regular wire for a better way of stabilizing the whole structure. I present my finished tensegrity structure supporting the cube. I can confirm the base is attached to the cube through the metal wires which also stabilizes the tilting and sway of the whole thing. The base isn't in the middle as I wanted but I think it will work to my benefit.

    Small Update


    I am using a motherboard tray from Mountain Mod because I need easy serviceability and grounding of the motherboard to the power supply.

    [​IMG]



    This is a video of the case currently. It's hard to describe how I balanced the case. The base will be hidden once I figure out the theme of this case.

    I can see you having issues with weight distribution.

    I'm back after going through 24 weeks of full-time schooling. I've been working on this PC case whenever I can. Details below.


    I used leftover aluminum sheet metal in the back to make the front panel. I used Fusion 360 to print out fan dimensions with some clearance built for placing the fans in the case.,

    [​IMG]

    This is the right panel for the GPU, power supply, and HDDs.
    [​IMG]


    This is for the panel for the CPU.
    [​IMG]



    Here's what the finished result looks like. I'm using Artic P12 PWM fans on the right side and 140mm Noctua Fans from my NH-D15 cooler.
    [​IMG]








    For the inside. I'm reusing a bunch of plywood that came from the bunkbed my brother ordered. This plywood was stored in the garage. The plan is to join the plywood with dowel pins for ease of modding in the future. I will be painting these boards.

    This is the finished panel for the side holding the motherboard.

    [​IMG]


    This is what the motherboard looks like with the wood panel. As for the panel connecting to the motherboard. I made the measurement for the IO shield, but it didn't line up with the hole I cut. I'm still going to seal that area up. The 12V SLA battery is around 5lbs. I have determined that is the required weight to balance the case. The whole case weighs nearly 100lbs.


    My current setup
    • ASRock Fafatal1ty x370 professional gaming motherbaord
    • Segfaulted 1700x
    • 16 GB DDR4 2400mHz Ram
    • Ice Giant cooler
    • Gigabyte Aorus 1080ti
    • Corsair AX1200, that's the first version of the AX series

    [​IMG]

    This is what it looks like on the other side. A 1080ti Aorus GPU sits above. HDD and PSU are below.

    You can see from the photos there is plenty of space. People can say this is a waste and contributes to the size of the build. I did it because the GPU is the only component to generate more heat than the CPU, storage drives, and power supply combined at full load. By compartmentalizing components by heat generated, I feel I can get better thermals when the side panels are up. I will seal the interior from the outside to make sure airflow is directionally in and out in one way. I'm currently finding a solution to minimize the wires on the back of the case for the GPU. I'm 50/50 on the front IO ports. I might not include it in the final build.

    The benefit of the ample space is the space alone. It's hard for me put the words down. It's unlimited freedom to create complex dioramas. It's difficult for me to decide what to do. I know what the top will look becuase I have to move the wifi antennas to the top. I am balancing the overall look because a bland exterior will work in any room and last a long time in looks compared to a complex interior. I have decided to turn the interior into a diorama of some sort.





    I bought a Creality 3D printer to build this fan duct in one go. This will fit on top of the CPU cooler. This will get plaster and painted over.

    Extra stuff.

    [​IMG]

    These are the things I bought for this build. Stackable Phanteks drive cages, Artic fans, and 6-pin Molex connector specific to the Corsair AX1200 PSU. I will be taping into my PSU to power accessories which can include lights. I currently have implemented 1 special feature in my build that is not seen in any PC cases sold on the market. I have been using it for the past few weeks and it works well. I will not be revealing this feature until the build is finished. I know how public forums work and any idea published here is free for taking and can be commercialized by those with the resources. The feature is also a good one and easily implemented. Expansion is almost limitless on features added because of the open-source solution.
