    One of my prefered boards is OPiPCPlus, but there is also OPiPlus2E and many others !
    It all depends of what is your use-case ...

    I would suggest the orange pi zero plus with extension board.
    H5 Prozessor
    512 MB RAM
    3x USB 2.0
    Gigabit Ethernet
    Onboard WiFi
    SPI Flash

    Runs for me very reliable for over 2 years under Debian Stretch.
    No thermal problems... running without exclosure on myside...
    I use it for: websites/webservice, pihole, openvpn, oscam server ... below 50 degrees Celsius.
    It's around 19,45€ including delivery to Europe (where i'm living).

    We will offer an ECC option. The Rockchip RK3399 SoC itself doesn't have a memory controller that has ECC feature, however we are currently working with a SDRAM vendor that now offer built-in ECC feature inside the SDRAM directly. It's not impossible it will be available on day one.
    No. It is not a use case that make sense from our point of view. I don't believe there will be a lot of people out there with a USB Type-C power adapter that can delivered up to 100W. Plus the power circuitry (and the PSU) would be quite expensive.
    No. It's a pure M.2 SATA port. FYI it's share with the SATA port 1, so the combination is either ( 1x M.2 SSD + 4x HDD/SSD ) or 5x HDD/SSD.
    Yes there is a 128Mb SPI NOR Flash.
    Something we didn't disclose because too much info already on the picture, the USB Type-C has been designed with a 4-in-1 mode concept :
    - Display Port
    - DAS mode
    - Host mode
    - Serial Console Access
    We will explain more at a later stage... but it's quite a unique design we did.
    We wanted to make the eMMC a basic feature of our board. I mean what's the point to sell it as a module when you know that in 90% of the case your user should use eMMC instead of SDcard. It also help in term of software support to know that all user Helios64 user will have the same config, therefore we can focus on installation guide that use the eMMC.
    You guess right this is not just some bare bone carrier board with a SoC in the middle. Between the PCIe-to-SATA bridge, the 2.5Gbe interface, the built-in UPS feature, RAM, eMMC, etc... it adds-up quickly. We also paid a lot of attention on the different power rails, this is a premium design compare to all the RK3399 board out there.
    Helios4 was USD200 with the full kit (PSU, case, cable, fan, etc...), our goal it to try to be in the same ballpark. This time we will sell a-la-carte style, you can just buy the board alone, our with the case, if you already have a PSU then no need to order one...

    Fairly understandable.
    Cortex-A73 is by design (eg. ARM) using lower power and produces lower heat than Cortex-A72.
    Cortex-A75 even lower power and quicker than Cortex-A73.
    -So it will likely pay to choose the latter implementation over the former, even if the price of the CPU is higher.
    For build-farms and quick data-processing, it's interesting having high-speed CPU cores and high speed network (this can be spread out on several GbE ports or just a single 10GbE port). 2GB or 4GB LPDDR4 would also be attractive for this kind of configuration. Native 6G SATA would be a huge advantage here as well.
    For storage (eg. NAS), one could likely go with the old Cortex-A7, native 6G SATA support and 1GB to 2GB RAM (still 4GB will be interesting when you're using RAID configurations a'la FreeNAS, where each 1TB storage space requires 1GB RAM). Again as many (independent, full speed) GbE ports will be attractive for this configuration.
    If the CPU you choose have PCIe, you can basically do anything you want; just please don't waste the PCIe on USB3. Adding PCIe switches would be interesting too.
    As I've mentioned earlier, it's not easy to find an affordable board that has both native 6G SATA, GbE network and PCIe. I picked the EspressoBIN due to the low price and that it "technically" would cover my needs, but I've had many problems with it for several years. It still has problems when I make software-reboots (sometimes hangs), so that's a board I will not recommend. Some boards also have problems with the RAM being affected by EMI due to bad board design. The EspressoBIN was an empty promise; it can't be used as a router/firewall unless you add an external USB3-to-Ethernet adapter. The speed on the 3 ports is limited to 1Gbit for all three [eg. they share 1Gbps!], so I fail to see why they even bothered making the board more expensive by adding the Topaz switch.
    (Perhaps so that other board designers, such  as you, can learn from their mistakes?)
