Hello! I'm Matilda and need a little help. I've been a mac user all my life but recently decided to build a computer for gaming mostly, but also adobe software at some point. I've already got all the parts, and have gotten part way through assembling it, but the wiring is proving a little tricky. I've been looking at various videos and such, but thought I'd just ask. I've got all the parts except the SSD into the case, but I'm worried about doing something wrong and stuffing up the computer

Keeping in mind that I've never even really used PCs much, let alone build one, could I get some advice and help on the wiring? Even if it's just links to good videos, most of the ones I could find were really bad quality so I couldn't actually tell what was going on.
These were my parts:
CoolerMaster CM 690 II Advanced with Window
AMD Phenom II X6 1055T
Corsair CMX8GX3M4A1600C9 8GB (4x2GB) DDR3
Western Digital Green 1TB WD10EARS
Samsung SH-S223C SATA DVDRW Drive
Gigabyte GA-880G-UD3H Motherboard
Arctic Cooling Freezer 7 Pro CPU Cooler Rev2
OCZ Vertex 2 3.5" 120GB SSD
HIS Radeon HD6870 1GB
Corsair GS-600 Power Supply
(Also I got a Acer V223HQBD 21.5in Widescreen LCD Monitor, but now I'm worried about how it'll display colour, I'm interested in digital art and draw in photoshop/flash so colour display is kinda important... I think I had a bit of a temporary stupid when I decided not to check this before buying.)
Not sure what else to say, sure I've probably missed out some details. Any help is much appreciated.
