Hello all,

I am building a new computer and am buying both my HDDs (Seagate 7200 rpm, 500gb, 32 mb cache x 2) and both of my Disk drives (Pioneer) OEM, so I will not be receiving any additional cables. My question is: How many SATA cables and of which type (I vs. II etc) will I need to setup my HDDs in a raid-0 and simply setup my Disk drives? Thanks for your time and help!

u need 1 data cable for each drive. afaik there is only 1 type of sata cable.

You don't need special cables for RAID.  
 
Your motherboard should come with at least two SATA cables - some come with 4 or even 6. What kind of MB will you get?
 
If you have a huge case and need extra long cables you can buy them from newegg. It's best to get the kind of cable with a latch at the end.
 
I had a Pioneer burner once and I wasn't happy with it. Anyway, at least get two different burners so you get different software with them.
 

+1 @aevm, except that OEM burners may not include any software.  Get at least one Retail burner so you get the software you need to use it.  That includes a decoder, without which you will be unable to watch movies.

I was lucky, my LG burner was OEM but with software anyway (Nero Express 7, Power DVD 7) I guess they were trying to compensate for adding rip-lock. (LG has a feature in firmware that makes it very slow at ripping DVDs.)
Whatever burner you buy, read a review or two first to know what you get...

 
The latch will look like a small flat metal spring clip. If you see a little piece of metal on the connector, you are looking at the latch. Unfortunately, all the SATA DVD drives I have seen use the cheaper latchless cables.

Is not the latch the difference between SATA I and SATA II Cable end and SATA socket ?  They are interchangable.
