CPU/Mobo I am building a NAS pc build ❤️

Should i buy 2 seagate exos 20tb from there? For raid 1, is it safe enough for data integrity..?
With 2 drives, Raid 1 is your only option if you want data integrity.
It would give you 1 failover.

With 3 or more drives you can choose between more options with better space efficiency and speeds.

But is he also providing nas/data center HDDs. I may put important data..
They are heavy duty drives, but from the looks of it they're refurbished. Not particularly bad, but they don't really come with any warranties either ofcourse.
 
What's
Hello guys, i always wanted to have my own storage server and light virtualisation home server (no transcoding) so i was researching a lot and came to know that ryzen apu have great efficiency and actually a good option for NAS pc.

So i finally ordered the full pc setup from these site vishalperipherals, computechstore, shwetacomputers and elitehubs.

1. Cooler master mwe bronze 450 v2 (recieved already)
2. MSI b450m-a pro max ii motherboard, (2.5g lan which is a nice fit for NAS)
3. Gigabyte 256gb nvme SSD
4. 2x8gb Adata XPG gammix d35 (white)
5. I already have a ryzen 3 3200g from a friend, i upgrad and help build/setup his pc last year and now i basically got it for free with the stock cooler.
6. A cheap cabinet to hold the parts for now, NAS cabinet are too expensive. So i thought going with ant eSports si11, i will buy additional HDD internal casing and mount it somehow later.

(11.7k for the full pc setup brand new)

I am planning to buy these,
7. 2 piece of Seagate ironwolf pro refurbished from newegg. 5yr warranty 10tb@$130 (anmol's usa shipping)

What do you think, is the setup good?
Anmol's usa shipping? Where can I find it? And how much does it cost to ship? I want to buy ironwolf too but small 2 or 4tb ones
