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.
