So many choices for my first build! Any suggestions?

[Snaketank]

Keep in mind I'm from Canada so I will be linking to newegg.ca
I am also considering buying all of this from NCIX (http://ncix.com)as they price match and have low shipping costs (may cost about $20-30).
Now, for budget, I would say I'm aiming for about $1000 CAD. However, going over a little for a good improvement isn't horrible.
I also know that the more expensive products will generally be better, but I want the happy medium if possible.
I won't be doing too intense of things; general gaming (D3 and SC2); some photo and video editing and some recording.
Also, I have an existing soundcard that I would like to use with my new build.
Total budget excludes monitor, soundcard, and operating system.

I've listed several possibilities for most components as they are where I've been directed during my research.
Any comments or suggestions for something else is what I'm looking for.

Hard Drive(s): I'm not sure if this will matter much but I'm more interested in the 32mb cache and SATA 6.0Gb/s rather than 3.0GB/s. I don't think I'll use more than 500GB so that's a good starting point.

My recommendations would be:
HAF 912
HX650
Asus Maximus
GTX560 Ti
Barracuda 1TB
Hyper 212 Plus
This optical drive. http://www.newegg.com/Product/Product.aspx?Item=N82E16827135204
and you sir are on your way to an excellent build. :)

[Snaketank]

Oooo, speedy reply! :-)

Now what made you choose those? Are they actually good components that will work well together?

And the GTX560 Ti, is that the Gigabyte ($219) or EVGA ($259)?

[RickyTick]

They are solid "bang for the buck" choices.

There is a big difference between the 560, 560 Ti, and 560 Ti 448. If you are planning on playing more hard core games like Modern Warfare 3 or BF3, or Skyrim, then the best option is the 560 Ti 448. Otherwise the regular 560 Ti is more than adequate for playing anything out there.

[Snaketank]

Ya, I'm not going too hard into gaming, so based on what you said, the 560 Ti does seem like a good fit. Thanks!

Anyone else have any opinions on these items?

:-)

You made some very good choices. Very similar to my build! The 560 Ti is a great midrange card that will run almost anything.
