Hardware recommendations for a pure media station?

[DingleBob]

hey, thanks for your input.
I'm in the process of creating a shopping list:

Already got some items noted down: 

• CPU: Intel Core i3-12100, 4C/8T, 3.30-4.30GHz (https://geizhals.de/intel-core-i3-12100-...#offerlist) @ 120€
  
• Motherboard: ASRock H610M-ITX/ac Mini ITX Motherboard (https://www.asrock.com/MB/Intel/H610M-IT...dex.de.asp) @ 120€
  
• RAM: 2x Crucial 8GB DDR4-3200MHz Memory (https://geizhals.de/crucial-so-dimm-8gb-...26575.html) @ 20€ each
  
• OS Drive: Crucial P2 M.2 2280 250GB NVMe SSD (https://www.amazon.de/Crucial-CT500P2SSD...KGSC1?th=1) @ 40€
  
• Media Storage: 2x WD Red 4TB 3.5" 5400RPM Internal Hard Drive (https://www.idealo.de/preisvergleich/Off...gital.html) @ 110€ each
  
• Network Card: Intel Gigabit CT Desktop Adapter (https://www.idealo.de/preisvergleich/Off...intel.html) @ 42€
  
• Power Supply: EVGA 450 BT 450W 80  Bronze Power Supply (https://www.amazon.de/EVGA-450-BR-Bronze...B07FLLB9N8) @ 50€
  
• (CPU Cooler?)
  
• Case: ?
  

Main question: How does this setup look? Is everything compatible and does it make sense? Did I make some silly picks? Any suggestions?

@TheDreadPirate you wrote, not to go for below 500W on the power supply. why exactly? wouldn't 450W be enough?

I'm so far at around ~650€ but I still have to pick a case. If some picks are an overkill, let me know.

Also: Do I need a CPU Cooler or will it be fine without?
