Hardware spec

Hi

I am building my first proxmox server for a client and he wants to go down the custom build using standard pc parts not server hardware.

I have come up with the following specs - anything pop out that maybe a problem? help is much appreciated. (missing a cooler / case i know )




Its going to be used for about 10 windows 10 / 11 vm's to run some backup software or python scripts for moving data around the network, nothing heavy.

Thanks anyone and everyone for reading!
