If you're in the market for a computer but are short of space or are looking for something small to run your looped retail sales promo instore, fanless mini computers that run Android, Linux or Windows are ready to meet your needs. Barebones systems allow buyers to pop in their own RAM, storage and other modules for a custom setup. Germany's Shuttle has announced just such a system, the XPC Barebone DL10J which can run 24/7 and be optioned to include 4G LTE. "It is ideal for use as an office desktop PC, as a fixed or mobile digital signage player or as a control PC in industry," said Shuttle's Tom Seiffert. "Just like its predecessor, the DL10J is a highly reliable choice and thanks to its non-moving parts, it is even suitable for constant 24/7 operation." The 19 x 16.5 x 4.3 cm (7.4 x 6.5 x 1.7 in) DL10J is built around a Gemini Lake processor based on Intel's 14 nm architecture, namely a 2.7 GHz Intel J4005 Celeron dual-core chip with Intel UHD Graphics 600. Buyers will need to throw their own memory modules into the two SO-DIMM slots, up to 8 GB, and there's enough room inside for a 2.5-inch SSD drive and NVMe solid state storage. Two USB 3.0 ports sit out front, along with an SD card slot and audio jacks, and there are four USB 2.0 and two serial ports around back, which have three monitor connection options as neighbors. The DL10J can be cabled up to a router via the Gigabit Ethernet port or wirelessly connected over 802.11b/g/n WLAN, but an optional M.2 adapter cuts the ties to home, office, retail or industry networks by allowing the mini-PC to connect to 3G or 4G LTE mobile internet. Idle power consumption is only 5 W, which goes up to just 17.6 W at full tilt, and the mini Linux/Windows-compatible computer is compact enough for placement behind a monitor with the help of the supplied VESA mount. Pricing for the Shuttle DL10J system starts at €168 (about US$200), and it's available now. The following promo video has more. Product page: XPC Barebone DL10J
