I am using this box currently as a bittorrent-seeder with qbittorrent-nox. The web-interface is nice. Today I built an embedded-server kernel for it. It seems to be doing quite well so far, but there were problems with the Sandisk-Ultra-USB3 (32GB) storage-stick, I am using there. It cannot handle all compressed filesystems, installation of PC-BSD (with LZ4-compressed ZFS-root) on it failed. After that the stick seemed to be defective, but it resumed work upon completely zeroing it. Today there was downtime, I spent much of the day, moving seeded files around, defragmenting and balancing, now it is running again, and the wattage is surprisingly low: 8W, although the files, it is distributing need to be decompressed permanently, because they are on LZO-BTRFS. The maximum wattage, I saw, was at 14W. I have done some online-research and found VIA-nano devices are rare, there seem to be quadcores in mini-ITX format, but this configuration is without SMP. With the stock-kernel dmesg looked like this: . ..
