Someone at MSI messed up yesterday it seems, and went live with a video detailing a new fanless line of mini desktop PCs. We don't mind the leak, though, as MSI looks to have used Intel's 7th Gen Kaby Lake processors to create a completely silent desktop machine.

The video was discovered by FanlessTech, it shows two Cubi 3 Silent Series mini PCs (black and silver), which use a 15W Kaby Lake U-series mobile processor and an aluminum heatsink for cooling the chip. No fan is necessary. However, to aid cooling the aluminum case looks to be open at the top.

Use of a mobile Kaby Lake chip and passive cooling will certainly limit performance, but the Cubi 3 Silent machines are no slouch if they can handle two 4K monitors. There's also ample connectivity with four USB 3.0 ports, two USB 2.0 ports, HDMI, DisplayPort, Dual LAN, a headphone jack, and even a COM port.

Since the video released MSI has followed up by making the product page live. In terms of size, the case measure 6.28-by-2.74-by-4.34-inches and weighs no more than 1.36kg (3lb). That's small and light enough to mount on the back of a monitor, and MSI will include the mounting kit to do just that.

It looks as though the Cubi 3 will ship as a complete system running Windows 10 Home, but I wouldn't be surprised to see barebones models appear, too. MSI is touting easy upgradeability, after all, with space for up to 32GB of 2133MHz DDR4 RAM as well as a single 2.5-inch HDD/SSD and M.2 PCI-e/SATA SSD.
