If Your homelab ESX have not sufficient RAM (8 GB for 6.0 and 10 GB for 6.5) is possible to pass hardware check 🙂

vCenter 6.0 – run:

installer.exe "SKIP_HARDWARE_CHECKS=1"

vCenter 6.5 – edit file:
vcsa-ui-installer\win32\resources\app\resources\layout.json
set:

   "tiny": {
        "cpu": 2,
        "memory": 4096,
        "host-count": 10,
        "vm-count": 100,
        "disk-swap": "25GB",

Aaaaaaand done.
