Coolby ZealBox Intel J4125 Mini PC

The Coolby ZealBox is a common entry-level mini-PC, but the port configuration is very interesting. Mini-PCs have always been in demand for niche applications due to their nature, so a product with a special hardware configuration like this would probably attract a lot of attention.

Regarding the specs details, the specs table on the product page says there is one USB 2.0, but from the image, two seems to be correct. As for the microSD card, the product image says “TF Card up to 256GB”, but there is no slot in the image. It’s probably best to assume that there is no slot.

The Celeron J4125 CPU, 8GB of memory, and 256GB of M.2-connected SSD for storage are the standard configuration for entry-spec mini PCs these days. It’s good enough for office work, browsing, video playback, simple image editing, and using illustration software with a focus on line drawings. The OS is Windows 10 Pro, and considering the nature of the mini-PC, the Pro version is a huge benefit, since it makes a big difference in usability just by being able to host a standard Windows remote desktop. It is also said to be upgradable to Windows 11, but I think it’s better to just assume that this is possible with the specifications.

The most notable feature of this mini PC is its special port configuration. The basic premise is that since this is a mini-PC, it will be operated by connecting a power supply, keyboard, and display. Therefore, the configuration of the ports is extremely important depending on the purpose of use, and that configuration is quite interesting.

The first thing you’ll notice is that there are a total of six USB Type-A ports: two 2.0 and four 3.0 ports. That’s a lot for a low-cost mini PC. However, there is no USB Type-C, which is odd.

There are three types of display ports, HDMI, DP, and even VGA, and it claims to support triple displays. Well, I guess simultaneous connection of three different types would be a bottleneck for the processing power of the CPU. Anyway, it’s good that there are variations.

And there are two audio terminals, AUX and MIC. This is quite unusual for a low-cost mini-PC. Of course, you can’t expect the quality to stand up to serious audio input, but with the abundance of USB (if you want to do serious recording, you’ll probably want to connect a recording device to the USB), it seems to meet the demand for a somewhat light audio mothership.

The exhaust slit of Coolby ZealBox is a nice accent to the design. Let’s take a look at the port configuration. The video output port is on the back, and the USB port is on the left side. Hmmm, a unique configuration. One of the things that bothered me is that the video output ports and the USB ports in particular are placed very densely together, making it hard to use the DP with other video outputs, and the USB ports seem to interfere with other ports, making them incompatible with USB memory devices of a certain size.

It supports up to 1TB of M.2 SSD, up to 3TB of SATA SSD (Note: I may have mislabeled HDD as SSD), and up to 256GB of TF card (microSD card). The M.2 slot has a 256GB SSD in it from the start, and the 1TB maximum is supposed to be a “replacement” rather than an “expansion”. the SATA slot is for expansion. This is orthodox for a mini PC. One thing I don’t understand is the microSD card slot, I can’t tell where the slot is from the image. Well, the image of the board is just an image, so there may be a slot inside, but there is also a possibility of a mistake in the description.

The VESA standard mount is available, which is a standard feature of mini-PCs. The mounting parts are also included.
