My home NAS: HP ProLiant MicroServer

My old NAS system was dying, I need to found a new one…
Here is my new setup:

• HP ProLiant MicroServer (using a special 100€ french user cash back offer, valid until the 31/10/2012)
• 8 GB of ECC RAM
• One 3.5 hard drive mounting bracket adapter for 5.25 inch bay (for the CD/DVD bay)
• One SATA cable with right angle connector
• 5 SATA hard drives, 2TB each
• A customized BIOS that unlock the SATA mode of the CD/DVD bay (locked in PATA mode in the official BIOS)
• A 2GB usb key (there is an USB connector inside the box)
• A HP MicroServer remote access card (not mandatory)
• Lian Li EX-50 Expension box
• 5 SATA hard drives, 1TB each. They came from my old NAS.

I've found lot's of advices regarding the setup of the HP MicroServer on TechForum.
Before installing FreeNAS on it, I'm playing with a small FreeBSD 9.0 installation on the USB key.
FreeBSD was installed without any package neither the port-tree: I'm using pkgng with my own package repository (thanks to poudriere).
The only problem that I found, was to correctly disable moused: A simple moused_enable="NO" in the /etc/rc.conf is not enough, I need to add moused_ums0_enable="NO" for disable it.
I've create 2 raid-z pools: A first with the internal hard-drives, a second with the external drives.

Now I've got lot's of disk space for my files:
