New Custom Computer [Need advice]

[Helpmeh]

Currently I have a custom-built computer, but I didn't take the risk of building it myself. I was initially planning on upgrading a few parts here and there in the PC, but I realized it would make a lot more sense just to build a whole new computer myself.

So far I've selected:

• AMD FX-6300: 6x3.5GHz, 14MB Cache, 95W OR AMD FX-8350 8x4GHz, 16MB Cache, 125W (only $50 more, one day sale)
• Kingston HyperX 2x8GB (should I get another set of 16GB?), DDR3 1600MHz, CL10 (what does that mean), 240-Pin DIMM
• OCZ Vertex 4 VTX4-25SAT3-128GB SSD
• Ultra 3.5" Internal Enclosure (for the SSD, is it necessary?)
• Asus Sabertooth 990FX R2.0, AM3+ mobo, ATX, DDR3 up to 1866MHz, SATA3, RAID, 8-CH audio, Gigabit LAN, USB3.0, PCIe 2.0, CrossFireX
• XFX HD-687A-ZHFC Radeon HD 6870 900M Video Card, 1GB GDDR5, PCI-Express 2.1 (x16) (is it compatible with 2.0?), 1xHDMI, 2xDVI, 2xMini DisplayPort (never gonna be used), DX11, Dual-Slot, CrossFireX
• Cooler Master RC-942-KKN1 HAF X ATX Full Tower, 230mm Red LED fan, 6x5.25" Bays, 5x3.5" Bays, 4xUSB 2.0/3.0, 2xAudio Ports (mic and line out on front), 9xExp Slots
• Cooler Master R4-LUS-07AR-GP MegaFlow Case Fan, 200mm, Red LED
• Asus DRW-241B1ST 24X Internal DVD Burner DVD, 2MB cache, 24x write to DVD+/-R, 8x w to DVD+RW, 6x w to DVD-RW, 16x r from DVD, 12x w to DVD-RAM, 12x r from DVD-RAM, access time 150ms (what does this mean?)
• Thermaltake TRX-750M TR2 Modular Power Supply, 750w, 80 Plus(what exactly does this mean?), 4x PCI-E, 6x SATA

Could anyone give me any tips/pointers for installing, or answer the questions that I've included in the list? I'd like to hopefully become part of the Self-Built Computer Club soon.

Sadly, most of the products I went out to purchase today weren't available because of the boxing day sales. That being said, I did purchase all that was necessary and I'll put the specs up as soon as I can.

Boxing overshadows personal computers?
In what part thereof planet d do you live?
Why not just order on line?
What you need to think about is if the motherboard is compatible with the Video Graphics you want.

Solid State Drive? Have you done it before?  RAID is still the better choice.

My point is that there are other things you can do as a hobby other that doing YAGM. (Yet Another Game Machine.)

Or,. just go to Newegg.com and they have recommended DIY projects for gamers.
Use what they recommend as a starting point.

Hope you have a good outcome.

The main thing for not buying it all online was to save on shipping costs.

The SSD was not for the extra storage space, but for putting some games that would appreciate the higher read/write speed.
