The new 4x4 BOX-R1000 is basically the active cooling version of the iBOX-R1000 model launched in April 2019. It comes with a smaller chassis, but the specs are almost the same, except for the supported RAM that has been downgraded from DDR4-3200 to DDR4-2400. Users ca still opt for the AMD Ryzen Embedded R1505G / R1606G dual-core / quad-thread CPUs with Vega 3 iGPUs.
