I am looking to build a Catalyst with this equipment, does anyone see any issues? Thanks in advance!
Bill

Mac Pro -
Two 2.26GHz Quad-Core Intel Xeon
6GB (6x1GB)
Mac Pro RAID Card
640GB 7200-rpm Serial ATA 3Gb/s
640GB 7200-rpm Serial ATA 3Gb/s
640GB 7200-rpm Serial ATA 3Gb/s
ATI Radeon HD 4870 512MB
One 18x SuperDrive
Apple Mighty Mouse
Apple Keyboard with Numeric Keypad
Apple Mini DisplayPort to VGA Adapter

Active Silicon: LFG4 (4 composite inputs)
VGA2USB: Switch live from any VGA input
TRIPLEHEAD2GO
Sonnet Allegro USB 2.0 (for internal Dongle)
M-Audio Fast Track Pro (for audio output)

Right now we will not be using this with a lighting console, so artnet or DMX is not needed at this time.

Any suggestions? Do I really need to use an SSD or will two 640GB 7200rpm drives in a raid be okay? Mostly will use 1 to 2 layers only at a time. Thanks!
