Should I build from used, from new, or use my current PC parts and treat myself to a cheeky upgrade?

Newbi here - keen to learn by doing.

I've run out of free cloud storage and I'm all in on becoming self relient for photo backups etc. Hopefully I can help out the rest of my family too.

I'd also like to run an e.g. Valheim server for my mates (typically 4 of us).

Lastly, I think I'd like to do some home automation stuff at some point down the road, but I haven't really started to learn about that stuff.

My needs are obviously pretty low end. But here's the question:

Do i build a NAS with second hand stuff I can find on marketplace, or do I use my current PC parts and upgrade instead?

It feels like the CPU's going on marketplace in my area are still worse than what I've got, but only just...would I be daft to get second hand hardware that is...almost as old as what I'm currently running? Also most folks are wanting to sell whole systems which come with a bunch of stuff i don't want to pay for (GPU, old storage that I don't want to be touching etc.).

 

Current build:

CPU: Intel Core i7-8700K 3.7 GHz 6-Core Processor
    
CPU Cooler: be quiet! Dark Rock 3 67.8 CFM Fluid Dynamic Bearing CPU Cooler
          
Motherboard: Asus Prime Z370-A ATX LGA1151 Motherboard
     
Memory: Crucial CT8G4DFS824A 8 GB (2 x 8 GB) DDR4-2400 CL17 Memory
 
Video Card: Gigabyte GAMING OC Radeon RX 7600 XT 16 GB Video Card
 
Power Supply: EVGA 650 GQ 650 W 80+ Gold Certified Semi-modular ATX Power Supply

 

For example, this is selling near me for £150. Would it do for what I want?

Power Supply: Corsair CS650M full modular Processor

Intel i74790K 4GHz quad core socket 1150 processor

Cooler: Phanteks PH-TC12DX air cooler in red

Motherboard: Asus Maximus VII Ranger ATX

RAM: 12Gb Corsair & HyperX mix DDR3 memory Graphics card: 6GB Asus GTX1060 Dual OC

 

I don't want to be spending loads of money for the sake of it. I guess I'm looking for value so if spending more is the right thing to do I'll do it, but equally I don't want to be wasting money on stuff I don't really need.

Grateful for advice!

So the specs are a crap shoot, if you are just going to run a NAS and a few app's you dont need much, ": im on an i3 8350k 32gb ram" but if you plan to add more in the future you might want more horse power. I would say any 4th gen I3/5/7 should run a nas with no issues, the thing youll wanna calculate is if you have power use concerns or if you wanna expand in the future what would be needed.

Thank you for the reply!

 

Wow ok - down to 4th gen makes me feel much better about getting something second hand and really cheap. I think I'll go down that route and just give it a go.

On the CPU front will ANY CPU consume low power when it's idle? Or do you reap the benefits of a low TDP when idle too? I do want it to be low power when it's just sat there.
