Compact copper-encased 14.2-liter PC system weighs 47.4 pounds, doesn't need fans for cooling — passive ITX case is nearly twice as heavy as the aluminum shrouded version

There’s a compact new fanless chassis on the block, dubbed the FanlessVC2300S DT (machine translation). Listed on China’s Taobao online market (h/t FanlessTech), what makes this particular design remarkable is that an all-copper edition is being made available, limited to 10 units. It is going to be extremely tricky to snag one of those, we expect. Still, the aluminum-clad version in the image appears to have the same total passive cooling capacity of 250W.

The physical presence of the FanlessVC2300S DT is certainly its raison d’être, so let’s consider this aspect of the design first. Whether you opt for the majority copper or aluminum shrouded version, you will receive a 360 x 303 x 130mm case with an interior volume of 14.2 liters and an essentially copper passive cooling system inside. The limited-edition copper-encased version weighs in at a hefty 21.5kg (47.4 pounds), according to the specifications, while the aluminum alloy model is approximately half the mass at 11.2 kg (24.7 pounds).

As per the headline, this is an ITX form factor chassis. Thus, you can equip your own choice of 170 x 170mm ITX motherboard in this quick-release system case. On the topic of max compatibility, there is room for a Flex ATX PSU, with a Platinum-rated model recommended. You will also have room for a pair of memory modules with a maximum height of 44mm, and a single 2.5-inch storage device.

Moving on to the technical details, according to the chassis maker, you can fit a CPU and GPU, adding up to a TDP of as much as 250W. A half-height Nvidia GeForce RTX 5060 is reportedly the most powerful option that works in this machine. That will likely contribute approximately 145W or less to the thermal budget. So, you’ll have 105W cooling capacity left for your CPU if you want to push your luck.

However, we can’t be sure whether you can split that total 250W TDP budget however you like between the CPU and GPU. That’s because, upon reading through the (machine-translated) specs, it appears that two separate thermal solutions are addressing these hot components. The blurb suggests that there are “a total of seventeen 8mm heat pipes to provide heat conduction for the CPU.” Meanwhile, the GPU is cooled by a trio of vapor chambers linked to a 10mm heat pipe. Both parts are also connected to the “four-sided heat dissipation structure,” which is hewn from copper fins, providing an effective 1.3 m² heat dissipation area, according to the case maker.

On the Taobao retail page, we see that the aluminum shell version of this case is priced at 1,760 Chinese Yuan (~$250) for an introductory period, rising to 2,000 Yuan (~$280) upon general availability. Also, you’d need to hire an agent or use some other jiggery-pokery to purchase it for delivery outside of China.

We couldn’t find any price/availability details for the limited-edition all-copper version.

    Never mind, that seems to be the aluminum case pricing...

    $280 seems like a pretty good price for nearly 50 lbs of copper.

    As of September 12, 2025, the market price for copper is $4.65 per pound or about $10.25 per kilogram. These are global market prices that are subject to daily fluctuations.

    How are the memory and the VRMs and such on the videocard cooled?

    Seems kind of cool for a system with an gpu integrated in the cpu, but I’d have my doubts putting in a discrete cpu.

    The ryzen cpu with the 8060s igpu would be really cool for a system like this if it’s available on an itx mainboard.

    I'd love to see a detailed diagram, but my guess would be that there's one vapor chamber for the VRMs, one for the RAM, and one for the GPU:
    "the GPU is cooled by a trio of vapor chambers linked to a 10mm heat pipe."

    Even better would be using it for the Ryzen AI Max 395+! According to the power data I've seen on Framework's implementation, 250W is an ample power budget for that processor. In Performance Mode, Phoronix found it averaged 98.5W and peaked at 160.8W:

    I miss the days when we didn't need a giant slab of copper to run a fanless PC. Well, except for the power supply of course.

    My old PS/1 Consultant, how I miss thee and your rackety Canon hard drive.

    My friend, I must inform you, your complaints are silly! You can run older hardware easily with KolibriOS! Not linux, all assembly!

    It just depends on what YOU want to do.

    "The copper version weighs 21.5 kg, while aluminum – 11.2 kg." how the hell does it weight 21Kg?! It doesnt make sense for 30cm x 30cm size box. Maybe tower PC's fully assembled surpass this small empty box.

    SBCs, like Raspberry Pi or even ODROID-H4 (which is x86) can be run fanless. The Pi 5 performs roughly like a Sandybridge and is fast enough for light-weight desktop usage. The ODROID-H4 performs more like a Skylake i5.

    From the look of it, won't do much. Only seems useful for old 32-bit x86 machines, and even then you're quite limited.

    I'd take a passively-cooled Pi 5 over that, any day of the week!
