That should be possible, I have also already included special standoff mounts for the HD plex 800w, and I'm not sure if you would really want more than that all things considered. Also I am not abandoning flex, I find dedicated self cooled PSU's to be much more reliable than AC adapters, but I have made it so that the design may be configured with FLEX or Pico based upon user preference.

I forgot to post it last time, here is a sneak peek at the shorty config. P.S. going forward I will be modifying the main design to allow compatibility with Pico style PSUs, as well as FLEX of course. I am currently working on parity between the expensive sheet cut sections so that every configuration will only require 3D printing to reconfigure, which is a lot cheaper than sheet cutting. I will also be mocking up an optional mod to the liquid cooled chassis to add two additional 40mm dual radiators (and fans) stacked with the 60mm dual rads for 1.6x radiator capacity. Hopefully I won't need it, but if the 60mm can handle 5950x/5700 xt, then adding these additional radiators might be able to further improve cooling for even more powerful graphics.

Small update, I am currently figuring out my printing situation for the second prototype, so while I'm waiting on that I've been making some final tweaks to the model. I've added some small QOL changes such as removable panels around the radiator tube mounts so that a T line can be run for an external fill/top off port. I am also working on a second alternate configuration based around server style air cooling, that will feature a dramatically shortened rear section, as well as compatibility with pico style PSUs rather than the standard FLEX ATX. The wattage limit will be a fair bit lower, I am hoping for/expecting at least ryzen 5/3060 to work comfortably, and possibly ryzen 7/3070 with more "laptop" type temperatures. Additionally, pico PSUs are easier to power off of battery, so the internal gpu slot may be optionally reconfigured to house a large capacity battery, requiring an APU build. This alternate config will be fully cross compatible with the standard janktop chassis, only requiring a swap of the three rear 3d printed chassis elements, and a swapped bottom cover. I also expect this variant to be much lighter (not including battery) due to the reduction in weight from air cooling and pico PSUs. I would estimate a portable rig with this config could weigh 12-15 pounds as opposed to the standard's hefty 18. P.S. The existence and availability of cherry MX ULP switches has come to my attention. Theoretically, a ULP mechanical keyboard would fit within the size constraints of the janktop without modification. I may make an optional open source mechanical keyboard for the janktop, with the possible option of a quick release to pop the board out of the palmrest, allowing it to be used as an external keyboard, and temporarily further improving chassis airflow. I'm really glad that I've taken the time to polish the model before constructing the second prototype, as many of these alternate configurations would not be cross compatible without some small modifications to the base design. Thanks for sticking with my everyone, I hope to be printing and assembling sometime in the next month.

I got a p4000 to boot over HDMI for m17x R2, but the internal display didn't work with it. It might be possible via display modification (which I think I've seen someone on the german fourums do) or via internally routing the HDMI to an inverter board, and then using a compatible display with the inverter. Maxwell is definitely the most powerful practical option though.

That does work in the m17x r2 however, it was a long time ago but I was able to use hwinfo to bind the second GPU fan to CPU temp and ran a 920xm at roughly 70-80 watts iirc with decent but higher temps.

Actually, modern 18 inch displays are usually 16:10 as opposed to 16:9, and based off the general sizing specs for 16:10 18 inch displays it should actually be possible to slot a modern 18 inch 16:10 display into the new assembly, with nothing more than a swap of the 8 bezel components. Great idea for an alternate design actually, thank you! As for larger sizes, I do plan on designing a more performance oriented janktop with further improved power supply and cooling, provided there is sufficient demand for such a device. I may also design a smaller slimline janktop designed to function more like a typical laptop, but with modular hardware. For now though, I just want to make the 17 inch as good as it can be since it's the perfect size for a jack of all trades machine. I will definitely be designing that alternate bezel in the near future however, as it sounds like an awesome idea that still fits within my current chassis design.

Hi Everyone, Sorry for being gone for the past couple of years, I've had a lot on my plate and not much time for R&D on a very important to me but not exactly profitable project. However, I have gotten back to work and am all but ready to print my second and hopefully final prototype in the next couple of months. Anyway, I just wanted to update everyone on where I am and give a little heads up that the project is still alive and kicking, even if it has been a little stagnant for a while. I'll be making a Much more detailed post in the future once I've built the second prototype, but for now I'll leave y'all with some sneak peek images at my redesigned chassis and custom display assembly, as well as what can be expected from the project in the future. Changes vs Prototype 1 New, fully custom sheet metal backed display housing with compatibility for standard 17.3' 16:9 laptop displays (16:10 may be an option one day as well if desired) Replaced 40mm triple radiators with 60mm dual rads, more capacity, better use of space, quieter fans, and considerably cheaper GPU slot rotated 90 degrees, more internal clearance, better GPU compatibility, GPU better protected from damage. (260mm dual slot gpu compatiblity for std. , 340mm dual slot gpu compatiblity for halfrad config) Muscle car style front air intakes, which double as optional front firing speaker grilles. Massive left side air intake Greatly improved keyboard slot Uses common cabinet style friction hinges, can easily be re configured for many different models of hinge. Optional slot for laptop style webcam modified to USB Huge improvements to Aesthetics, Durabiity, and Ergonomics! And of course an all new JankTop logo! It should also be possible to use a server style direct mount heatsink alongside standard rear mounted fans and airflow channeling to air cool the cpu and gpu for a much lighter and cheaper albeit less powerful configuration. This will be a great option for anyone who wants to use the case now, and upgrade to more powerful hardware in the future, or for not performance oriented setups, such as an air cooled APU system driving a portable storage server. Prototype two will also feature considerably higher specs, and full watercooling, so we should get to see what the general practical cooling capacity will be (5700xt+5950x) A major benefit of the combined loop is that any slack in utilization on one part will result in more cooling for the other, which means performance should be stellar in lopsided workloads ( e.g. gaming[high GPU medium CPU] and video editing[high CPU low GPU](usually)) Thanks everyone! Let me know if you have any questions or suggestions 🙂

JANKTOP 4.1 - NOW WITH 4090 SUPPORT >:) The title is pretty self explanatory. Both the stock 4.1, and 4.1 halfrad designs are now ready for testing. Since my friend plans on printing one, I won't release the files until she's done that, assuming she still wants to, as it may help me iron out any kinks and design flaws. That said, the design is now vastly improved over the prototype, with better cable management, cooling, durability, aesthetics, and much more! And since the halfrad config supports up to 335mm long dual slot blower cards, there is now officially support for the new blower 4090 in theory, which should perform 1.5 - 1.75x that of a laptop 4090. Here are a couple of sample pictures of the new design: P.S. You know how the prototype had bad GPU thermals? Well it turns out I was wrong about that, as the 5700 xt model I have actually normally runs around 80 c, even with good airflow, which means even with the much worse ventilation on the prototype, temperatures weren't actually too much higher than an idea airflow case.

More to come soonish, but good news! I got access to my CAD software again, and design has resumed with the help of a newfound friend. I'll get more in depth othe 4.1 build I'm planning to have done in coming months, but for now, here's a sneak peek on the progress:

Just adding on, I have slotted Intel AX200 in M17x R4 using cable and slot adapters. It requires a small amount of chassis modification to fit, but worked fine and was pulling speeds in excess of 400 mbps.

Unfortunately, I'm running into the snag of needing to learn a new cad software, but I have a ton of QOL changes planned for the next iteration. First and foremost, I'm going to redesign the palmrest and skeleton chassis elements to give the radiators an extra 20mm of space without really increasing chassis size, in order to slot 60mm double radiators as opposed to 40mm triple. These rads are also a bit less wide, so that leaves more room for the power supply, and I may even be able to get rid of the "Flare" at the back of the machine. This will knock about 70 bucks off cost of radiators + fans, but will also increase cooling capacity significantly. I'm also planning to rotate the gpu slot 90 degrees with the I/O pointing foreward, and put the ports behind a folding panel to protect it. This change will also require a much shorter gpu riser cable of only like 250mm as opposed to 600 which will greatly improve cable cost rarity and stability. I'm also planning to implement a "trackpad" using a small touch display rigged to act as a pointing device for the large screen, while it's display may be used as a sensor panel or such. Finally, I'm going to redesign the display assembly to be compatible with modern EDP displays, and possibly add an optional locking mechanism. I will add the current design is quite sturdy, and the mini itx i/o doesn't really need covering, it's already recessed. (this revision may be delayed due to stated cad issues, and current lack of R&D funds, but I assure you it will continue once I have stable income) Also, as for the prototype, it has it's fair share of small gremlin issues, and I have yet to waterblock the GPU (might wait for bigger rads for that), but it's still going strong. I daily drive it without too many issues for work and gaming.

Super impressive build! I'm curious, what power supply did you use that can supply enough wattage for a 3090? I love the minimalist aesthetic. If you want an help with 3d printing, I'm happy to help. No pressure though.

I've done a lot more thinking about the concept, and i won't forget it, but it's getting shelved for now. I may redesign it around a framework laptop motherboard as well, as the lattepanda is quite weak. That said, I'm picking up the Janktop 4 once again, and I expect the 4.5 design to be finished around Christmas, which will include a fully custom display assembly and support for modern 17.3 inch displays. I'm also going to be getting my hands on my own 3d printer, so not only will the updated design finally be making it's way into a real machine, but I may be able to sell chassis kits on commission much sooner than expected, if there is demand.

I've been toying with the idea of designing a much smaller Janktop type machine with a battery, good battery life, and decent performance, but with some very cool and nice features that will come in handy during hardware development. I recently learned about the Lattepanda alpha single board computer, which has a decently fast efficient quad core CPU, 8gb ram, 64gb emmc, and two m.2 slots. The really cool thing about it though, other than the small size is it's built in Arduino and serial i/o pins. The reason I'm so draw to this is for one thing, it's actually possible to connect a laptop keyboard through that serial i/o and get it to input, meaning this Janktop could have the same massive keyboard compatibility as the 4.0. On top of that though, and Arduino can be used to program eeprom chips, so I could integrate a slot for a chip or test clip directly into the laptop. That's not all though, as the second m.2 slot is type b and can be adapted to pcie 16x. The idea would be to also have a pcie 16x slot somewhere on the laptop, that can be used to test and utilize desktop graphics cards externally. The egpu would be powered by a pico psu, and you would have to plug a big old 330w or so power brick into an auxiliary input jack in order to use it. That said, the rest of the machine would work fine without the second charger, it would just be needed for the EGPU. Ultimately, the goal with this concept is not to create something that's all that powerful, but rather a lightweight developer laptop with good battery life, decent modularity, and some really niche useful features for hardware developers such as myself. Additionally, you could use whatever keyboard you want, which is a big plus nowadays considering the god awful chicklet keyboards on most thin and light machines. Target size would be 14 inches, with extended rear and an inch or less thick. What do ya'll think of this idea? I know it's not as modular as the 4, and while I would like it to, certain sacrifices do need to be made for size and effeciency. It's not meant to be an improvement either, just kind of the other half of the project, a portable, efficient machine with decent modularity and niche developer features to go hand in hand with the giant clunky op beast. The 4 can always be remote accessed as well, and that's actually what I'm doing with mine right now in college most of the time.

Just letting everyone know, there is a new thread in Custom Builds, and the STL files are now accessible via GitHub.
