ASRock has quietly added a new family of ultra-compact form-factor (UCFF) PCs into its product lineup. The Jupiter-series one-liter systems are designed for Intel’s Coffee Lake processors and feature rather robust expansion capabilities.

The ASRock Jupiter-series UCFF PCs are compatible with various Intel’s 8th Generation processors with up to 65 W TDP and are based on Intel’s H310 or Q370 platforms, thus aiming at different segments of the market: from entry-level Pentium-powered PCs to higher-end Core i7-powered desktops. Both H310 and Q370 Jupiter machines feature two slots for DDR4-2666 memory modules (up to 32 GB is supported), an M.2-2280 slot for PCIe 3.0 x4 or SATA SSD, two 2.5-inch/9.5-mm bays for storage devices, an M.2-2230 slot for optional 802.11ac + Bluetooth module, and so on.

While the systems seem to be generally similar internally, they have a number of differences when it comes to connectors and features. The Q370 platform supports Intel’s vPro technology and is therefore more suitable for enterprise users. Next up are connectors. The H310-based machine has three display outputs, including a native D-Sub as well as a DisplayPort and an HDMI. By contrast, the Q370-powered one has two DPs and one HDMI. There is still an option for a D-Sub, yet it is available only for custom-made orders. Meanwhile, there are also differences in USB connectivity. While both do have USB-A and USB-C on the front, the more expensive one supports USB 3.0 speed on the back, whereas the cheaper one has USB 2.0 due to the chipset limitations.

ASRock already lists its Jupiter H310 system on its website, so expect it to hit the market shortly. The Jupiter Q370 is noted only briefly, so most probably it will arrive a bit later.

    Is the 2x USB-C ports an industry first for a non-laptop form factor machine? I don't recall seeing it anywhere else before.
  • shabby - Thursday, September 27, 2018 - link

    Definitely a first, it's a miracle!
  • deil - Thursday, September 27, 2018 - link

    Very close to perfection. Exactly what I wanted... missing two detais... Vesa mount and internal PSU. I will try to put this behind monitor on vesa. wish me luck
  • sandtitz - Thursday, September 27, 2018 - link

    deil, an internal PSU on a computer this size is crazy talk, because it supports up to 95W CPUs. That much power just needs a PSU half the size of this computer itself.
    If they enlarged the chassis with space for it - you'd be stuck with a hard to replace, proprietary form factor PSU.

    I hate to say it, at the risk of being categorized an Apple fan boi, but the Mac Mini does it, and the PSU's rarely, if ever fail.
  • BurntMyBacon - Friday, September 28, 2018 - link

    That's a fair assessment. Still, the custom PSU would increase costs and AsRock isn't exactly known for their high profit margins, so the extra cost is likely to be somewhat significant to the overall price tag. Can't say for sure until we get a price on these, though.

    Mac Mini also doesn't use a desktop processor.
  • edzieba - Thursday, September 27, 2018 - link

    There are a few motherboards with a Type-C on the rear panel plus a Type-C front panel header.

    About time, USB A - is so late 90's in designed. Yes they increase to USB 2.0 in 2000 and USB 3.0 in 2008. But no real redesigned until USB-C
  • Lord of the Bored - Saturday, September 29, 2018 - link

    And twenty years later, USB A and B are STILL better connectors than USB C in almost every respect. Hell, so are the mini-USB connectors.

    The age of the design isn't what matters. Sturdiness and reliability matter. Cost of implementation matters. Ease of use matters, and I grant it is a problem with USB A(somehow they figured out the B side needed a key, but forgot about the A side).

    USB C is a fragile and complex(thus expensive) form-over-function design that makes me ashamed of what passes for electrical engineering these days. I'd rather have a bare pin header(HexBus!) than USB C. The USB C connector is almost as bad as SATA.
