Nano Frog, how many Optical Bays does the 8 Core have? I thought it only had 4 for HD's? Or am I totally wrong? Also, can I specifically ask Apple where I want the drive to be?
There are 2x optical bays. One of them contains an optical drive, the other is empty (base config). Unless the second optical drive option is selected in a BTO machine, of course.
It makes a convenient location for SSD's/HDD's beyond the 4 bays.
As per physical location for a boot disk (or any other), it doesn't matter. You set the boot drive in Disk Util. Apple doesn't allow location instructions, even in the BTO site that I've seen.
Regarding the 640GB Boot Drive. I place the OSX on this. Also I place Paralells and Windows XP on here right?
This will all depend on what drives you have when you setup the system.
If you want RAID0 via OS X, you'd be better to install OS X on the array, and leave the 640GB for Windows (whatever flavor). You'd still need a backup system for everything you want to keep.
What I don't understand though is this - if I use the 640GB as boot BUT only Raid the 4 1TB's (which will hold my media) how would this speed things up? I thought that if you Raid'd the Boot Disks (eg 2 640GB's) then this would speed things up!
If you use the 640GB for OS X, and the array for data, only the data will be sped up. By placing the OS on it, it gets the benefit of the additional throughputs as well. (Yes, RAID speeds things up, but only what's contained on the drives, and OS & data DO NOT have to be separate at all).

The software (video/graphics apps) you listed, will be able to benefit from a stripe set (RAID0). Additional memory would be highly recommended, possibly more than the 6GB you're looking at. It's also easier to do on an 8 core model than the Quads. It also makes better sense to use 2GB sticks rather than 1GB versions, just in case you do have to go with a smaller number.
Get your upgrades 3rd party anyway. Cheaper, and you have more control over what goes into your system.
So assuming you do go for a stripe set, it's best to use the 640GB as the windows disk.

The reason is, it CANNOT be placed on the array. It just won't work.
What on earth is Boot Camp? I'll go Search this.........
It's mainly a partition tool that allows Windows and OS X to be installed on the same drive (single disk systems).
For back-up I'm going to use an external HD connected via FW800. Is this a good idea?[/QUOTE]
Nanofrog states several things to do with that spare 640 GB drive. He/She says to either use it as backup or install Windows on it, since OSX's RAID utility and Windows partitions don't work too well together, if at all.
He.
Windows CANNOT be installed on an
array created by OS X.
gugucom proved this beyond any reasonable doubt jsut recently. For single disk systems/usage, it can with the Boot Camp utility.
Which model SSD do you guys recommend? I see 2.5 inch SSDs but hardly any 3.5 inch ones.
Intel's.
The only 3.5" SSD I'm aware of off the top of my head (and even worth having), is the 1TB OCZ Colossus. It's big, fast, and $2300USD.

They even dropped the MSRP by $200USD.
