Noooooooo, I forgot to sign up! I didn't even realize it was October. Boy this last year flew by. Well good luck everyone else, have fun!

This is a super clean and most excellent built! The controller ports as USB ports is a fun idea too, especially with the mouse that you have there. I'm assuming you made that mouse, right? Looks awesome. I would love for you to upload those STL files somewhere too, would be a blast to try my hand at cramming some stuff in an NES one day.

Alrighty then, all the parts have made it in and it's time to finish this thing......for now of course. I'm sure I'll want to change things around more once I get my hands on a 47X0G APU. Anyways, got the radiator in and tried to use the stock barbs at first, but they were just too big and the angle of them wouldn't have worked with the pump anyways. So those got chopped off and new holes drilled. I was originally planning on soldering in those brass G1/4 to G1/8 adapters, but I again decided to try to route of less resistance and just tap the aluminum. It had a decent amount of thickness from the base where the barb went through the tank, so I decided I'd go with that first. It's not the greatest fit, I had to bend the edges of the metal away to get the fittings to seat and still had to use plumbing thread tape to be sure. I originally ordered 2 radiators just in case I messed one up. The second one hasn't arrived but I think when it does I'll most likely try the soldering method on that one. Because of the outer diameter of the G1/4 to G1/8 adapters I got I'll probably have to turn those down so that they can actually fit in the side of the tank as it doesn't extend super far out from the body of the radiator. Little bit of leak testing and bleeding of the system just to make sure. These are not the final tube lengths, just some that I cut to test with. Next I test fit it on the system and ran some proof of concept tests to make sure it would actually get enough airflow to cool anything. Didn't bother changing the tubes yet. As you can see the "clearance" that the Festo fittings have to the RAM clips is about -0.4mm. Luckily the little clips have just enough flex to allow the pump/block to fit with the fittings installed. Now we come to final assembly. The tubes had to be shortened, one by about an inch as it wraps around the bottom of the CPU block, the other needed to be only about an inch as the radiator inlet and pump outlet fittings ended up basically touching. You can just see them on the left in this picture. You can also see how cramped everything is in there. I still think I might be able to squeeze a 2.5" SSD next to the RAM, that might be a plan for the future. Next went in the PSU to really squeeze the last of it in there. Also decided it would be a good idea to somewhat insulate the radiator from the C15 plug there. Threw on the top cover with the fan and this is what you get. Without the Noctua A9 sticking out like a sore thumb it looks even more like a bog standard PSU in there. If there weren't the GDC Beast cables sticking out the front and the rear I/O, you'd be hard pressed to notice that it's actually a watercooled PC in there. As for cooling and thermals, well that's another story. I did a little testing with the L9a in there before hand and the temps for Cinebench R15 runs go to about 70C and by the end of an R20 run it was peaking around 80C. Not the greatest of tests or testing methods, but it's at least something. Running with the watercooling I see R15 runs stay in the ~65C range and R20 runs hit ~77-80C still. So all in all, not much better cooling than an L9a, but at least not worse. The future will probably see a new APU, maybe a 2.5" SSD or two, and potentially replacing the radiator with one that has soldered in G1/8 adapters. I'm sure I won't get to any of those any time soon as who knows when the APUs will arrive in the US consumer market, plus I have an idea for a 3L custom brickless case that fits ITX motherboards and a full size GPU. I think I'll work on that next....

Some more progress has been made. Not much but lots of little pieces to source in order to make it work so far. All the pieces together and ready to get to work. An M11x1.0 Bottom out tap (North Bay Cutting Tools on Amazon) to make the threads, the silver pieces are time-sert part #01281 (G1/8 inner thread and M11x1.0 outer thread), the Corsair H60 pump, and the elbow pieces are G1/8 thread Festo NPQH-L-G18-Q8-P10 parts (same that [USER=7161]@petricor[/USER] used in his S4MAX build, thanks for the help!). I'm not sure if it is a necessity, but I went with a bottom out tap so that I could get the threads as deep into the body as possible to avoid issues when driving in the time-serts. The brass pieces there will be used on the radiator later, they are just some cheap G1/4 to G1/8 adapters from Amazon. Using the tap made quick work of the plastic. Luckily the threads aren't tall enough to punch through any of the sidewalls. Because of the small roll pins that held in the original tubing I can't rely solely on the Festo fitting to seal the threads. So just to stay safe I used some plumbing tape to wrap the outer threads of the time-sert and make sure it would actually seal. The Festo fittings o-ring can handle the inner thread seal. Just stick these things in here... And bam! Doing things the wrong way because I was too cheap to spend $200 on the right tool, I used a bolt with the wrong thread pattern to cross thread in and drive the time-serts home. The plastic would give way before the threads of the bolt or time-sert would, so it's pretty safe to do that way. Either way, the time-serts screw right in and fit super flush in the body of the Corsair H60 pump. No drilling or cutting required. Add in the Festo fittings and I've got myself a low profile, semi custom, H60 pump/CPU block with standard G1/8 compatibility and no need for an external pump anywhere in the system. Ready to go on the CPU and only 28mm from the top of the IHS. I've leak tested it for the past two days and not seen a single drop come out. However, it was a pain in the ass to bleed the air out. I'm very happy with how this came out

Well, I got it in my head that I might be able to water cool this thing. The Corsair H60 pump/block is one of the shortest ones I could find which should help squeeze it all inside. I ordered some parts earlier this week and the H60 was the first piece to arrive. Time to check it out and see what I got. I gave it a quick test on a bench machine I've got laying around and all seems well. Fires up, makes a little bit of pump noise but once the bubbles settled it was acceptable. Woohoo, the internet didn't lie! This thing is actually only 28mm thick. Gonna have to read the lines though since the battery died on my cheap digital calipers. Looks like if I take off the plastic cover with the Corsair logo I can save about 1-1.5mm. Might need to do that to save as much space as possible, but my initial measurements say I shouldn't need to. We shall see. Obviously I can't fit a full size 120mm radiator and these long, thick tubes. So looking for a way to remove the tubes I found these little pressed in roll pins on the bottom. Luckily if you take off the plastic cover on top you have access to the other side of the pins. Using a small bit from an iFixit kit to get in there did the trick. I was able to do one by hand but the other needed some extra force, I just squeezed it out with some channel locks. Bam! And they are out just like that. Now what else holds those tubes in? Looks like just some rubber o-rings. They slip right out pretty easily. Nice. And we're left with just the bare pump/block. Now let's see what's under this cold plate. Just 8 Phillips head screws hold it on. Another job for the iFixit kit. Doesn't look too bad, seems alright at first glance. Looking a little closer it turns out there was some gunk starting to form and needed a little bit of cleaning. Overall not bad, this was a pretty good buy, I'm happy with it. After cleaning it up it's time for reassembly. It's not perfect but it's definitely better than it was. Anyways, I'm not worried as I think the limiting factor will be the radiator as I think I can only fit an 80mm one inside the case. Back together and waiting for new fittings and the radiator to get here from China. Next update might not be for a while depending on how long the shipping takes.

Lol, and lucky for me that Solid Gear PSU was only $20. Left me with no guilt when ripping the guts out.

Yeah, the Deskmini is a great system in itself, this was more for fun. I originally built it planning to put a 4000 series Ryzen APU in there (the Deskmini A300 only supports APUs) but I'm not sure if Asrock will supply an updated BIOS for this motherboard to add compatibility for them. They are planning to release a X300 model when the 4000 series APUs come out. I might upgrade to that if I have to, but if I can get away with a simple BIOS flash I'd much prefer that option. I also bought some parts last night to now try and watercool this thing. Wish me luck.

That's the board I'm using. I just have a deep-seated hatred for external power bricks. Plus, I liked the novelty of using a standard PC power cable to power the thing.

I built this little guy to bring to LTX this year before the current climate had set in. Figured I might as well show it off in here since the event was cancelled. So here it is, my Power Supply. Link to the full album on Imgur. https://imgur.com/a/WqHYFbB My litte PC. Cheap little power supply, nothing too special. Seems ordinary enough. Cables hanging all over the place and looks fine. But what's that noctua brown doing under the normal fan? Well, opening it up reveals an STX motherboard out of a Deskmini A300 and a 300w FLEX PSU running an AMD 3400g with 16gb of DDR4 and a 2TB NVMe drive. Had to do some hackery to get everything to fit. So all these components needed to get moved to the back of the PSU, mainly to make space for the fan but also because I had to ditch their heatsink. So now they just have a thermal pad and dissipate heat to the outside case. Also had to drill some small holes where the standoffs meet the case in order to mount the thing. Another thing that needed to move was this little capacitor on the front side. I didn't have room for it in the back and the fan didn't leave enough space to leave it where it was. So I got a new capacitor and left the legs long. Threw some heatshrink on them to insulate them and bent it out of the way. Seems to work fine. Of course I had to include some well shaped plastic behind the PSU to insulate the case, I didn't want any chances of things touching back there. Like I mentioned above, the fan and the PSU didn't like trying to both exist in the same spot. So not only did those PSU components need to move, but the fan also needed to lose some weight. There was a lot of the fan frame cut away. The thing is actually pretty flimsy without it being mounted to the top of the case. I also needed to trim all the front I/O off the motherboard in order for the PSU to sit low enough in the case. That and to fit the GDC Beast PCIe X4 version. I needed every single millimeter I could get to make the PSU and fan fit together. So much so that I had to bash as flat as I could the little divits that lowered the fan into the case. It may have gotten me only 2mm but it helped a ton. And since this motherboard was originally supposed to run on an external 19v DC power brick, the barrel connector had to go so I could solder on an EPS 12v cable. And yeah, those solder joints aren't my best work, but those pads are tiny and those wires are massive. Of course with that GDC connected to the M.2 slot, that means I can run an external GPU. I ended up going with a Radeon 5700 non-XT as it was the most powerful ITX GPU I could find to actually buy. I had to buy it from Amazon Japan, but at least it was in stock. Oh, and did I mention that all the PSU cables hanging out there still actually work? They actually power the GDC and GPU. I was originally planning to do this elaborate rear I/O setup, but after making my initial test cuts I was happy enough with the way it turned out that I decided to leave it be. Keep it simple. A close-up of the rear I/O shows the flaws, but it works fine for me and I was able to keep close to the stock powercord mounting location. It had to move up a little to clear the USB/Ethernet tower, but not by much. All the parts laid out ready to go with me. The nice thing about this litte setup is that because it's an APU in there, I don't necessarily need to bring the GPU and GDC with me, but I have the option of having that extra horsepower if needed. I mean I guess it's still pretty impractical to have all those wires all over the place, but hey, no one is perfect.

Looks like I hit 1 billion points a little bit ago. Woohoo! Didn't think I'd see that until the end of this year sometime.

Haha, I know them feels. I've got a few more places up the ranks I want to climb before I call it quits for a while.

Lol, that would be so heart breaking.

Haha, no worries. I was just joking, thanks for the hard work putting on the event and good luck with the work still ahead of you. God speed my man.

Did I meet the requirements? I hope I got enough WUs and points.

I've got at least one more day in my systems. I'll be keeping them all up until the morning of the 6th. After that though I will start setting them to FINISH and commence the cleanup.
