For an operational system, you still need CPU, RAM, storage (2.5" HD, SSD M.2 or 2.5") and an operating system.

By the way, there is already a successor to this barebone, the Asrock X300, which also supports Ryzen 4000 CPUs, but is not yet available at Digitec.

It comes with the case, external power supply and the system board. I have also ordered:
- CPU AMD Ryzen 5 3400G (AM4, 3.70GHz, 4-Core) - supplied fan does not fit into the case of the A300.
- Fan Noctua NH-L9a-AM4 (3.70cm) (almost inaudible)
- RAM HyperX Impact (2x, 8GB, DDR4-2666, SO-DIMM 260 pin)
- SSD Samsung 970 EVO Plus (500GB, M.2 2280) on top of the board or one/two 2.5" mSata SSD (bottom)
