Internal sounds like a great plan for your system; less expense, less connectors (vs. external solutions) to cause issues, and the case you have already sounds up to the job!
Internal raid is far easier and less expensive. A big tower can easily hold 8 or more disks, especially if you use drive cages from Supermicro or Chenbo. I currently have 17 disks and 2 BRD burners internally with room for 2 more disks.

WOW! That's a lot. What is the size of your power supply? Any recommendation on controller that our not too expensive?

My PSU is borderline, it is only 1000 W and 1200 would have been better, but was not yet available when I built this system. I currently have an Areca ARC-1680iX-12 with BBU and 2 GB cache, but may need a new server in the near future (the current one is getting pretty old) and am considering to move my Areca card to this new server and getting an Areca ARC-1880iX-24 with BBU and 4 GB cache for my video system. Not exactly cheap, but a fabulous card that lasts a very long time. Unless of course Areca plans to introduce a new line of controllers with PCIe 3.0 capability, that one may expect to coincide with the introduction of the Sandy Bridge E line of CPU's in Q3/Q4. I have asked them about their plans, but have not yet received an answer.
Thanks for all your help.
Harm I got a 3ware 9690SA-4I Storage controller (RAID)
Here are the specs:
Controller Interface Type Serial ATA-300 / SASData
Transfer Rate 300 MBps
Buffer Size 512 MB
Supported Devices Hard drive, disk array (RAID)
Channel Qty 4
Max Storage Devices Qty 128
RAID Level RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50
Compatible Slots1 x PCI Express x8 - low-profileBottom of Form
With four 1TB drives what raid should I use with this card Raid 6, 10, or 50?

With 4 disks, use raid5. It gives the best speed/storage balance while giving you redundancy in case of disk failure.
As a very rough indication of performance and net storage space in comparison to a single disk, this is what you will get from each raid, assuming 4 disks:
Raid0: Speed around 380%, storage 4 TB, no redundancy, no safety
Raid5: Speed around 270%, storage 3 TB
Raid6: Speed around 170%, storage 2 TB
Raid10: Speed around 190%, storage 2 TB
Raid50/60 is not possible with this limited number of disks. Raid1 only applies to two disks.
These are very rough indications of speed gains and depend very much on the IOP on the controller and the driver, but should be accurate enough to give you a feeling of what to expect, but please don't hold it against me if I'm off by a couple of % points.
Thanks again for the advice.
Harm, i have a question: do you use 2 separate machines ? (1 server for your Areca rig connected to your NLE machine )
I'm thinking of upgrading to an Areca configuration some day but wonder how you use yours
BTW thank you for the amazing advices you always give on the disks setup !!!
Thank you for your answer !
And wow, that's some setup you have there !!!
