DIY NAS Hardware setup?

Hey Lemmies,

I'm planning to build my own NAS/Server. Because it has been a while since I last build a computer from scratch, I was wondering if you people could tell me if my setup is sufficient for what I'm planning to do with it.

This is the hardware I'm planning to buy:

• Case: SilverStone SST-SG13WB - Sugo Mini-ITX

• Motherboard: ASRock J5040-ITX Mini-ITX Mainboard with Intel Quad-Core J5040ASRock J5040-ITX Mini-ITX

• OS SSD: Crucial P3 Plus 500GB M.2 PCIe Gen3 NVMe + glotrends M.2 NVMe PCIe x16 Adapter

• Storage: 2 x Seagate IronWolf 4 TB, NAS HDD, 3.5 Zoll, 5400 U/Min, CMR, 64 MB Cache, SATA 6 GB/s, Expandable to 16TB or more

• Power: be quiet! System Power 9 ATX PC 400W

• RAM: Corsair Vengeance LPX 16GB (2x8GB) DDR4 3200MHz C16 XMP 2,0

I want as a minimum a capable NAS for media streaming with Transcoding for 1080p in good quality and Backup/Storage of Data in a RAID setup for data security. On top of that a few services like PiHole, Home Assistant etc. would be nice.

Is this hardware sufficient or am I missing something? Can I expect good media streaming?

Thanks!
