quick thoughts: scrap that power supply and get something more stable, maybe a corsair hx750, hx850, or hx1000. an asus or gigabyte mobo would be better and less expensive. the asus p8z68-v is quite good. look at the corsair vengeance or g-skill ripjaw memory. they're only 9 or 10 bucks more. about that cpu, why get the 2600 instead of the 2600K? spend the extra 20 and get the good stuff.

If this your first time assembling a PC from components, I strongly suggest that you put the components together in stages. This will minimize potential damage and maximize troubleshooting any issues. Power down after each step!

1) Install the motherboard and power supply in the case, but do not connect the power connectors. Power up the power supply and use a voltmeter to check the voltages.

2) Do NOT install the CPU, memory or cards, yet. Connect the power supply connectors to the motherboard, power up, and look for smoke. The moment you smell anything, power down and review your motherboard installation for possible shorts with the standoffs.

3) Install only the CPU and the cooling fan. Don't forget the silicon grease! Connect the case speaker to the proper connector. Connect the fan to the proper motherboard connector. Power up and check that the fan is turning. If everything is good so far, you should hear a beep code from the speaker which indicates that the CPU is running.

4) Install the graphics card and keyboard. Connect the monitor. Power up and check that the BIOS displays error information.

5) Install one of the memory cards, power up. Check that the BIOS recognizes the memory.

6) Install the remaining memory cards. Verify that the BIOS recognizes the total memory installed.

7) Install and connect the hard drive data and power supply connectors, Verify that the BIOS recognizes the type and capacity.

8) Ditto for the Blu Ray drive.

9) Install the remaining cards.

10) Install the operating system and enjoy your accomplishment!

MadDeez  a hx1000 ?i a 1000 watt PSU  is cabable of running 3 way SLI with 3x GTX580  you can run that rig without any problem on a 600 watts power supply that has a high efficiancy meaning +80.
its even possible to power 2 x 560GTX ti in sli on that setup with an 600 watt PSU...it just depends if you care or dont about noise. A 1000 W would be silently singing in the breeze on this setup no doubt. Or get yourself a modern 87+ PSU 
I do agree on the Motherboard gigabyte are cheaper and have almost the same stuff ( you might want to check the Zx68-UD3P for example also comes with HDMI and USB 3 and they have 12 phases or more + IT WILL BOOST YOUR HDD up to 40% + see the link below.
Since you postet an 2600 ( intel i would suggest getting an intel board with the correct sockel since the one u posted last is AmD
example : this one would work ( http://www.newegg.com/Product/Product.aspx?Item=N82E16813128506 ) and i would think about getting the 2600k if you already buy 2600 why not the one with free multiplier ? EDIT didnt see the MAD link but still i recommend intel
No CPU cooler listed ? - Do yourself a favour and dont go with the boxed cooler get yourself a good cooler everything is better than the intel boxed standart cooling system. ANy will be better than the boxed
RAM´s: Gskills ripjaws are good... but it all depends of what timing you want- ADATA is also strong these days C9 on DDR3-1600 + they have 10 years warranty !
( Sorry if i say this now but getting yourself a 1000- 1500 USD Puter and a 50 USD case is strange a better tower will provide better Fans and therefore better airflow if your planning on cooling on air ) i suggest over thinking everything and maybee getting yourself a good case or saving a bit more money for it especially if you want to build a rig these days into a midi tower it is worth it. ) PC´s dont get more expansive they always drop in price so you dont loose nothing.

Anyway
This is how i build my rigs other people would do diffrent but this is how i do it:

1. Most important get yourself a free and clean workspace
2. Read the descriptions of your hardware ( very important if you have a good heat sink/ CPU cooler )
3. open the box of your motherboard and remove everything in it even the motherboard itself ( u can use the sealing of the mainboard on top of the box to coution / absorbing pressure -  Impact absorbing cellular plastic mostly comes with hardware all thats big enough to fit your board is good.
4. place your box on your workspace now get the anti static foil your MB was warpped i and place it on top of the box or the plastic add the motherboard on top.
5. open the cpu lock
6.Get your CPU and place it i7 have two  carvings on the outside + the board has the fittings for it...just make sure its fully sitted and doesnt move then close the lock.
7. Read the description of your CPU cooler
8 Apply Thermal compound
9 Depending of what kind of Heatsink cpu cooler you have ( if its a Huge cooler ) i recommend placing your RAM´s first.
10. Install CPU cooler
11. Install PSU into your case
12. Install MB incuding RAM and CPU cooler into case
13. Attach power cables and case cables  / no neefd to get them all nice and neat yet you can do that later if your rig wont turn on you probably have a cable on the wrong connector.
14. before you power up install graphics card and sound device if you have them.
15 leave the case open
16. before you connect your PSu to the wall socket / ectric socket make sure the switch is on / 0 ( turned off )
17. plug your mouse and keboard to your rig everything else can wait till your done with installing your OS
17. If your attachd to the socket flip the switch of the PSU
18. press the start button
19. check if fans are turning...
20. Go and setup your bios ( SSD performance  or to select your main boot device to install your OS ) gigabyte will have a quick option for selecting boot device...
21. Install your OS
22. Get yourself Antivirus and AntiMalware programs or install them if you have them ( suggestion Avira and Lavasoft AdAWARE )
23. UPDATE...Your windows
24. Restart - update - Until the updater says your done quadtripplecheck for updates now install your mainboard drivers if windows havent done so yet...
25. download graphics drivers install them reboot.
26. Install Stardock Products
27. Now attach your printers external drives whatever..
28. start coffee machine...and get yourself a cup some sugar and a cookie BC you earned it

totally agree with you just wanted to mention that the rig wont exeed the 1000watts in any way you could power two of those rigs with it
If there were enough cables
I Use the Noctua NHD14 for cooling and you cant install your ram if your CPU cooler is in place you have to unclip one Fan to mount them...

Added a picture cables are quite a mess but iam awaiting another noctua Fan to replace the loud Lian Li fan on the back.
Agree with the installation my description of the cooler told me also to install the cooler before mounting i guess it would be impossible to install it inside the case

yes indeed it is its the b25fb they dont have the side window this way you can put foam to each side to make the rig silent.Everything louder than moving air is not acceptable for me
The other version of that tower is the b25SB it is made as silent case and comes with noise absorbing foam already the only bad thing is that you have a fan less.
The lian li b25fb is only black from the outside ^^
I was original planning to get myself a corsair graphite 600T or the special edition 650 or a Silverstone SST-TJ07-S TemJin Big-Tower - or the Silverstone SST-FT01S ( midi ) all have a very good airflow and look damn good but iam glad to have picked the b25fb
So far these are the best options you can buy and all cases are timeless meaning that you can use them for years.
