question about OCZ600ADJSLI power supply, and case question

heres my system:

Motherboard: Asus A8N32-SLI Deluxe
CPU: AMD Opteron 165 1.8ghz (planning to OC to 2.4)
Ram: OCZ Platinum 2gb PC3200/DDR400 dual channel kit (2x 1gb)
Video Cards: 2x eVGA 7900gt CO (SLI)
Hard Drives: WD Caviar 250gb SATAII, Maxtor 80gb IDE
Optical Drives: Lite-On DVD-RW 8x
Floppy: Yes, staples brand.
Sound Card: Creative Soundblaster X-Fi Xtrememusic
Power Supply: OCZ Powerstream 600w Adjustable SLI


I noticed there are some 4-pin molex connectors that are on their own cable, they are labled "VGA/HDD". THey are not like the other 4-pin molex that have 3 or 4 connectors on a single cable. What are these for? They definitely don't fit into my VGA cards because my VGA cards (7900gt sli) take the 6-pin PCI-E connectors. So I should put it into my hard drive then and put the other one into my DVD-Burner ??

I have 2 hard drives. A main SATAII 250gb hard drive with windows xp installed, and a secondary IDE 80gb hard drive for backup and extra storage.

I have 5 case fans too that take the 4-pin molex connectors.

How should I hook everything up? Like this?


2x PCIe -> 2x eVGA 7900gt SLI
1x SATA power -> Sata hard drive
1x VGA/HDD 4-pin power -> IDE hard drive
1x VGA/HDD 4-pin power -> IDE DVD Burner
1x FDD Power -> Floppy
5x standard 4pin molex power -> case fans
1x 24pin -> motherboard
1x 4pin P4 -> motherboard


My case fans each have 2 connectors on them, one to take power and one to give power. Should each fan get it's own molex from the PSU, or can I split the power between the fans with just one molex since the fans have 2 connectors? I mean should it go like this

Molex -> Fan 1
Molex -> Fan 2
Molex -> Fan 3
Molex -> Fan 4
Molex -> Fan 5

or like this:

Molex -> Fan 1 -> Fan 2 - > Fan 3 (rear and side fans)
Molex -> Fan 4 -> Fan 5 (front intake fans)

??


Ok my next question is if anyone knows how the heck to mount two hard drives in this case:

I've had the case for like 2 years now, and I have just had my hard drives sitting in the bottom right drive bays just resting there. But I want to properly mount them for they don't move around when I pick the case up. Anyone have a clue how you do it? I can't figure out for the life of me how they go in there.
