An L1 for the uSFF club, 4.6L including 30W "brick"
Mobo: Asrock Q2900-ITX
RAM: G SKill SO-DIMM 2x4GB 1333
SSD: Samsung 128GB(actually swapped out from L2, package has a 256GB)
Wifi:Intel PCIE x1 slot card
PSU: Toshiba 30W 19V Brick + HD PLEX 150W(had it lying around way overkill)
Flash memory: Mfactors mini-PCIE to dual SD micro adapter
OS: Linux Mint
Case: Lone Industries L1
Decided to go with Centrino PCIE x1 card over mini pcie version as the card has antenna connectors built-in. May try out one of these for mini-pcie slothttp://www.mfactors.com/products/MR15-252d-Dual-Micro-SD-Cards-to-Mini-PCIe-adapter.html
Easiest, fastest boot up of a new OS I think I ever had, found wifi and all hardware without any help, typing this in from the new build which runs very snappy on Linux. Heatsink and brick barely warm to the touch.
So far idles at about 12.75W from the wall and highest I've seen is ~22W from the wall playing a DVD., brick consumes 12W alone, eerily silent.
EDIT: Got the mini-PCIE to dual SD micro adapter in, works great just need to get some 64GB SDs but pretty much this thing is built out as far as hardware options are concerned
Another EDIT: Got the 2x64GB Samsung EVOs on and put a USB bootable version of WIN10 preview ISO and successfully booted from that (contrary to what manufacturer says, probably more to do with your UEFI/BIOS capability) but Win10 setup would not select the other SD micro only SSD, may get cheap one to try interested to see how it handles that. Still have one SATA power and SATA-III connector left.
