My file server - comments??

[oldfart]

Hi Guys
I'm new to this forum (be nice)
This is what I built & why

Why first.
I wanted:
a large enclosure to put hard disks in - cooling is a problem where I live, it can reach 50C in the summer. And, I can't afford an a/c enclosure!!
I needed a file system to serve video files, mostly .mkv files in HD (they are mainly about 8Gb each). They are served to dreambox satellite boxes around the house (dreambox runs Linux).
Also to serve MP3 files.
And to download torrents (cough)
And hold 'other' files (cenral store)
I have about 6TB of files so far....

What it is:

CPU - Quad core Q6600 @2.4GHz
MB - Asus P5Q-VM
8GB memory
running Linux Mint 12

case Thermaltake Element V NVIDIA Edition

Raid card LSI 9650SE-8LPML
Raid 5

HD
6 x WDC WD2003FYYS-02W0B0
1 hot swap spare
1 old sata 2TB drive for the system drive

File system
GPT partition
ext4 format

Router - Vigor 2820

switch Netgear GS748T

UPS Salicru advance 2000VA

serves:-
4TVs
4 laptops
2 tablets
1 phone
4 dreamboxes
printer

everything is networked to the switch via seperate cat6 cable through a patch panel.
The router is direct to the switch.
