Replacing the stock fans
First thing I did was updating the bios to the latest version and replacing the stock fans by more silent fans, because this reduced the sound level significantly. I used the  Noiseblocker BlackSilent XM2, 40mm and Noiseblocker BlackSilent XM1, 40mm. Used the XM1 to blow air out of the asrock 330 Pro and de XM2 to blow air over the cpu and gpu.

Create XBMC Live DVD
I downloaded the XBMC Live CD from the [http://xbmc.org/download/]. Right click the ISO and choose [Open with] > Windows Disc Image Burner and burn the ISO to a DVD. Start the Asrock 330 Pro and boot from the DVD.

Rember username and password
Remember the Username and Password you enter during setup. It will be needed when you want to access XBMC remotely with SFTP.

Setting up SFTP root access, step 1
– Download putty from: "http://www.putty.org/"
– Start Putty and type in the IP address of XBMC to connect.
– Username: As entered during installation of XBMC live
– Password: As entered during installation of XBMC live
– Enter the commando: sudo passwd root
This will prompt you to change the root password, use the same password as entered during installation of XBMC live.
– Close Putty.

Setting up SFTP root access, step 2

Start a free program like WinScp or FileZilla and connect to XBMC live:
Host: sftp://xxx.xxx.xxx.xxx (IP address can be found in XBMC live on the System > Network)
Port: 22
Username: root
Password: As entered during installation of XBMC live

You now have root access to XBMC Live and can see/edit any folder on the system.

XBMC Settings

Enable SAMBA
If you want to access the internal hard disk of the asrock 330 pro, from you’re Windows pc, you can use SAMBA

Start putty and connect to XBMC live in my case: 192.168.1.19
Username: root
Password: As entered during installation of XBMC live

Enter commandos

– apt-get update
To update sources

– sudo apt-get install samba
This will install samba and start it running

– nano /etc/samba/smb.conf
This will open the samba configuration for editing

– Copy and paste the following lines at the end of the file
[xbmc home]
comment = XBMC Home Share
path = /home/xbmc
force user = xbmc
inherit permissions = yes
read only = No
guest ok = Yes

[xbmc system]
comment = XBMC System Share
path = /home/xbmc/.xbmc
force user = xbmc
inherit permissions = yes
read only = No
guest ok = Yes

– Ctrl + x followed by Y to save the file
– After rebooting the XBMC live, you can access the two shares created in Windows explorer by just entering the IP address, like \\192168.1.19
