GMK NucBox Teardown, Ultra Tiny 4K Windows PC

**Unboxing and First Impressions**

We're here to take a closer look at the NooBox, a compact PC that promises to deliver powerful performance in a small form factor. The device is housed in an aluminum case, which adds a touch of premium feel to this miniature computer. As we carefully remove the mid-case, we can see the intricate details of the PC's design and construction.

The NooBox features two PCBs: the I/O board and the main board. The I/O board houses the USB 3.0 ports, 3.5mm audio jack, SD card slot, and M.2 slot. This compact layout allows for a seamless integration of these components into the device's design. On the other hand, the main board is where all the magic happens, featuring an Intel Wi-Fi card with 802.11 AC Plus Bluetooth 4.2 connectivity.

**Removing the I/O Board**

To access the inner workings of the NooBox, we need to remove the I/O board. This involves carefully unscrewing the standoffs and gently prying the board out of its socket. As we lift off the I/O board, we can see the RTC battery connected to it, as well as two ribbon cables that connect to the main board.

**Understanding the Main Board**

The main board is where the CPU, RAM, HD, and power input are housed. It's clear that this device is designed with efficient cooling in mind. The main board features a full copper heatsink, which provides better cooling capabilities compared to previous models. This heatsink is attached to the upper case via springs, making it easy to install and remove.

**Thermal Testing**

As we perform thermal testing on the NooBox, it's clear that this device is designed to run cool and efficiently. The full copper heatsink does an excellent job of keeping the CPU at a safe temperature, even during intense loads. This is a significant improvement over previous models, which struggled with heat dissipation.

**Power Consumption Testing**

We also perform power consumption testing on the NooBox, and the results are impressive. Despite its compact size, this device is capable of delivering decent performance without consuming too much power. The power consumption is reasonable, especially considering the specifications of the CPU and other components.

**Conclusion**

In conclusion, the NooBox is an impressive miniature PC that offers a unique blend of compact design and powerful performance. With its aluminum case, efficient cooling system, and robust power supply, this device is sure to appeal to anyone looking for a compact PC solution. While there's always room for improvement in terms of size and weight reduction, the NooBox is a significant step forward in miniaturizing PCs without sacrificing performance.

"WEBVTTKind: captionsLanguage: enhey what's going on guys this is cta prime back here again today we're going to be doing a teardown on the gmk nook box now if you're not familiar with this i just posted a video kind of a full review running windows 10 this is a palm sized 4k mini pc it's got 8 gigs of ram 128 to 512 gigabytes of storage right out of the box and it's powered by the intel celeron j4125 overall for its price and its form factor i think this is an awesome performing little mini pc now if you're interested in seeing this thing in action check out my original video but since then i've had a few people asking me to do a quick teardown so that's exactly what we're gonna do in this video so first things first we need to pull the bottom off here as you saw we have those four rubber feet they're kind of glued on they have that sticky back you need to peel them off and then we'll remove these four screws the bottom should come off of this fairly easily and once we get this off we should be presented with the m.2 ssd that they have pre-installed now this one is the lower end version with 128 gigabytes of storage but you can opt for up to 512 in this unit and this is user replaceable so if you did end up with the 128 gigabyte model and want to upgrade it down the road you can always do that you're just going to pull this screw out here and the m.2 ssd should slide right out so they have made this pretty easily accessible and as you can see this is not an 80 millimeter m.2 this is a 42 millimeter m.2 next up we need to slide the mid case off this is aluminum here and i personally like the way they set this up with aluminum it does offer a little extra cooling for the whole unit itself some of the other similar mini pcs are made out of plastic and this kind of does up the build quality adding this aluminum case here so as you can see this whole unit is comprised of two different pcbs we have the i o board and the main board and i love the way they've set this up it's connected with a ribbon cable and this is how they're able to fit this in such a small form factor the bottom board is what i call the i o board this contains the usb m.2 slot and things like that and the upper board which i refer to as the main board houses the cpu ram hdmi and power input so as soon as i pull these standoffs out we're going to remove this bottom plate here and we can now see that i o board we have our rtc battery connected right here and there's two ribbon cables that just need to be popped up we can remove that i o board completely so yeah like i mentioned this houses the usb 3.0 ports the 3.5 millimeter audio jack and the sd card slot and on the bottom as we saw when we pulled it apart this has that m.2 slot so yeah this is an awesome way that they've come up to keep the size down on these new units so as for the main board this is where all the magic happens we have an intel wi-fi card here 802.11 ac plus bluetooth 4.2 it has two antennas connected to it and it just routes around the upper part of this whole pc and it actually has some decent wi-fi and bluetooth range so now what i want to do is go ahead and remove the main board we have four more standoffs here that need to be unscrewed i'll go ahead and get these out and this should pull right out along with the heatsink well i'm not exactly sure if the heatsink is attached here it might just be attached to the upper case and it is attached just to the upper case so let me go ahead and unplug these antennas here just to get them out of the way and once i have these out of the way i can just remove the main board and this has a lot of thermal paste on it on the original model that i reviewed they were using a little thermal pad which didn't cool very well and it actually had an aluminum heat sink but this one here they're using thermal paste and a full copper heatsink so that's why we have much better cooling on this production unit really glad to see that they've done this but they could have lightened up a little bit on that thermal paste but i mean it did keep cool enough like it sits i won't add as much when i reassemble this unit but as you can see we do have that full copper heatsink in here and this does have a fan attached this is not a passively cooled unit it's an actively cooled unit there's just not enough metal in here to keep that cpu cool without a fan and it looks like they've used a little of this tape here to kind of keep this heatsink in place so we got that tiny fan with that full copper heatsink and this actually does a really good job cooling this j4125 cpu i did some thermal testing and power consumption testing in my last video so i was wondering why this heatsink was kind of taped in here it was taped in here loosely but then when i pulled it out completely i noticed that it's actually spring-loaded so these four springs make contact with the upper side of the heatsink to kind of push it down on that cpu and make full contact this is just another little upgrade that they've added to the production unit to keep this thing cooler really glad to see this so yeah i love the way they assemble these little mini pcs i mean there have been a lot of these little mini pcs or these palm size 4k pcs released xiaomi has one the chewy lark box the gmk nook box which we have here and i believe there's a few other chinese manufacturers coming out with these same style pcs and they all use this stackable pcb layout here but i mean this is a really good way to fit all of this tech into a super small form factor but that's going to wrap it up for this one really appreciate you watching like i said i had a few people asking me about a quick tear down so i figured i'd go ahead and create a video on it if you have any questions or you want to see anything else running on the nook box just let me know in the comments below and don't forget to check out my review video but like always thanks for
