What's on My Home Server
Currently i am running Proxmox VE 7.4-3 with couples of VM in my HP Prodesk 600 G2 with this config :
- Intel(R) Core i5 6400T (4 Cores)
- 12GB of DDR4 2133Mhz
- Nvidia Quadro P400 2GB
- Old WD Blue 160GB Hardrive
- PNY 240GB SATA SSD
Pretty much i got all of these with cheap price. I'm still not running much services on my infrastructure, so i think it's still enough for now. I also plan to add some more nodes, since i got spare AM4 motherboard with A320 chipset.
For the networking devices. I still rely on my trusty Mikrotik hAP-Lite series (Rb 941). Its get the job done since i live only myself at my small apartment. So the router doesnt handle too many devices or people.

I hope these setup inspire you to also build your own server.
Cheers :D
