I gotta second ikea. Though frankly, every brand will be slightly different in the color balance. If you want matching, you gotta stick to one brand it seems..
On Proxmox, I use the built-in system + storing it to my Synology NAS (RS1221+). I use Active Backup for business (filesync) to back up the Proxmox config files, and also backup the husband's PC and my work PC.
