SilverStone NJ450-SXL / Streacom DB4

SilverStone's 450W SFX power supply is so tiny that it can fit into the smallest cases, like in this already crowded (Ryzen 5 2600X / GeForce RTX 2070)  Streacom DB4. A heat sink case inside a heat sink case has us slightly concerned (OK, seriously concerned) but it seems to be working.
