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.

    This doesn't compare favorably to HP Elitedesk 800 DM G4 which is practically of identical size, but includes USB 3.1 Gen2 ports, Intel NIC (for those who abhor Realtek), and can be configured with Thunderbolt (or just extra USB-C port) and VESA mount (including mount for the PSU).

    Hopefully, the difference will be represented in pricing.

    The Hades Canyon NUC from Intel actually has 3x USB-C 3.1 gen2 ports (2 of which are also Thunderbolt 3 ports) and the whole system is smaller than this.
  • Eidigean - Thursday, September 27, 2018 - link

    Correction: smaller in one dimension, though larger in the other two.

    221 x 142 x 39 mm (1.224 L)
    178 x 178 x 34 mm (1.077 L)

    Both are considered UCFF.

    No thunderbolt support? Even on the more expensive one?

    I made an account just so I can start commenting on these small PCs.

    Please, please, please start putting dual intel nics in these. We literally will not buy any model if it lacks dual intel nics. Please, OEMs, grow a brain and start putting two intel gigabit nics in every small industrial / POS machine you make.

    I have a thin mini-itx system with dual nics, it's the same size as this. I think gigabyte still offers thin mini-itx boards with dual nics.

    That would actually make sense and increase the options you have for the system. I'm glad that at least someone picked up where Lenovo left off with their "Tiny Desktop" line.

    My name is BurntMyBacon and I support this message.

    Oh wow, if it would have had just one more ethernet port I think the homelab / home server crowd would have been all over it.
