I put this system together to stream a live broadcast of the local roller derby team. It's running VidBlaster Studio edition to switch between 4 HD cameras (I have 2 Blackmagic Decklink Duo PCIe cards installed for pulling in the feeds). Really a great system thus far but will possibly need to upgrade the CPU to an i7 as it is pushing the limits on CPU usage when streaming. This i5 was something I got from a buddy at a huge discount so no major loss if I switch it out.
The whole set up is in a Logisis 4U rackmount case that is housed in 6U flight case with a power distribution unit and vent taking up the other 2 rack spaces. I call it the Beast because it just looks like a seriously mean piece of equipment.
There are actually 4 of the seagate barracuda 2TB drives. 2 of them are set up in a RAID array fro recording the live footage. The other two are for storing the final edits and other media pool items used in the production. The SSD houses all the OS and program software.
If I get time to put them together I'll post the benchmarking results
