Bought this MDG computer in parts for $20 off Kijiji. Bought a Gelid silent 9 fan on sale for the cpu fan ($2.88).
Bam! That's it. No video card, E2140 1.6Ghz dual core, 1 Gb DDR2 RAM (667Mhz)
Ubuntu 12.04LTS with Openshot video editor. Filmed in 720p.
That's all you need!!! Seriously, not a $3000 rig. Just some basic bits.
