Am I Overbuilding My Home Server Setup for Over 1k?

Hey everyone! I'm planning to build a robust home server that will function as a NAS, game server, media streaming device, and possibly even a home assistant. I realize this might be overkill, but I want it to be powerful enough to last for years without needing an upgrade.

Here's what I'm considering:

- **CPU:** i5-13600k - €180 (used)
- **Motherboard:** Gigabyte B760 Gaming X DDR4 Gen5 ATX - €120 (new)
- **Power Supply:** Corsair RM650e - €80 (new)
- **Case:** Fractal Define R5 - €110 (new) / €70 (used)
- **Cooler:** 360mm Montech Hyperflow AIO - spare, already have
- **Boot Drive:** 512GB Lexar SATA SSD - already own
- **App/Gameserver SSD:** 1TB M.2 NVMe - €130 (new)
- **RAM:** 64GB DDR4 3200 (2x32) - €200 (used)
- **HDDs:** 3x4TB 3.5 Inch - €300-€400 (new)
- **Fans:** Arctic P14 5 Pack - €35 (new)
- **Possibly in the future:** GPU: Intel Arc A310 - €110

This setup would feature 2.5GB LAN, a strong CPU, and ample storage to last me for a long time. The total cost could be around €1365 if I decide to buy the GPU and go for the pricier HDDs. What do you think is unnecessary or should I consider changing out? I know a less powerful CPU could suffice, but I want to ensure I have enough resources for future expansions without needing to upgrade. I'm new to home lab setups: currently, I only run a Minecraft server on a ProDesk micro, but I'm looking for advice since I can't post this kind of inquiry in certain communities. I may also use this server to store and edit large clips for DaVinci Resolve.
