A server should be as

I bought this server and am very happy with it. I now do not repeat what others have already written, but jot down briefly my system compilation:
- HP N40L with 4GB RAM, on the concerns this recession
- Storage bay adapter to a slimline DVD-ROM and two additional 2.5 "-. To install hard drives Storage bay adapter - 8.9 cm to 6.4 cm (3.5" to 2.5 ")
- 4GB additional memory KINGSTON HP 4GB 1333MHZ DDR3 ECC
- USB 3.0 Card Delock 2 Port PCIe card (2x USB 3.0)
- SATA Card SATA 3 (6Gb / s) Card, 2 internal ports, PCIe
- Slimline DVD-ROM
- 2x 3TB- 3.5 "- HDD in RAID 0
- 1x 2TB- 3.5 "- hard drive from the old NAS as a backup disk
- 1x 80GB 2.5 "- hard disk drive as the operating system Open Media Vault
- 1x 640GB 2.5 "- hard drive for Virtual Box

Only downside is the electricity consumption, even if the hard drives disconnected. I let the server but shut down automatically when no computer in the network accessing it and unlock it by pressing a. On occasion I'm going to test a WOL software that automatically turns on the server when you start the computer.
