The DL20N series from Shuttle is an impressive jump in performance versus the older DL10J, while the choice to have installed a Pentium N6005 4-core SKU while retaining the 10W TDP is great! The whole system is passively cooled, so it is virtually noiseless if we do install only SSDs as storage devices. We have found that using the chassis horizontally is not stellar for the nearby M.2 SSD, because it tends to share a bit of heat from the Intel SoC heatsink, but in vertical position the issue is fully solved so purchasing the vertical stand is a must in our book!
