This tiny and full-featured board is a great foundation for building a small system. 9cm x 9cm x 3cm! It came with a slim fan (adds 1.5cm to height with grille), a 4-pin fan cable for a second system fan, a slightly large but good wall-plug power supply, RTC battery, 2 of their proprietary SATA cables, 4 tall legs for setting up on the dev bench, and well-packed for shipment. Barebone, but ready to go!
It's a lot of capability in a very small package. I'm building a compact server/NAS with the N355 and I installed 32GB and BE200 wifi, connecting my SATA array and both 2.5GbE. I'll forgive the lack of USB-C. The auto-poweron jumper and switched 12v output are a great inclusion. Idle power about 11W at the wall, rising to high 20's under load. Without the fan, it runs hot but stably - with the fan no problem and very quiet.
It has definitely been exceeding my expectations. Recommended!
