I am new to building/maintaining/servicing servers.
I had an old system lying around so decided to build it into a server.
I got a little experience in Proxmox but recently switched to HexOS (TrueNAS SCALE) and I am loving it.

My server specs:
Mobo: ASUS P8B75-V (with latest bios)
CPU: Intel i7 2600
RAM: (4x) 4GB 1333Mhz DDR3 (Total 16GB)
Storage:

• SanDisk 128GB SATA SSD
• (3x) Seagate Constellation ES.3 ST2000NM0033 2TB 7200 RPM 128MB Cache
  GPU: Nvidia GTX 960 MSI 4GB gaming
  PSU: Thermaltake Smart 500W
