This is a solid build.

Drunkducki,
will the HAF-912 be big enough to fit my components and will 16mb cache memory in my harddrive be enough.

Do You need an OS? Since you did not mention that you did not need it, I'll assume you need it. Then, your build looks like this:

Why do you not want an SSD? It is CRUCIAL for any computer built today. Do you have one already?
If you do not already have an SSD and have no need for Windows 7, swap out the OS for a 60gb SATA III SSD.
This is the OCZ Vertex III 60GB- it will give you tremendous speed gains for everyday tasks.

The GTX 560TI included is enough to play Most games @ high @1080p. The next upgrade worth taking would be the GTX 560Ti 448 core edition. The EVGA listed in the previous build would be the best for the price.
Rosewill's 550w HIVE 80Bronze power supply should provide enough power for most single card setups. A Radeon 6970 will fit in that power envelope.
A Hyper TX3 heatsink is included with the i5 2500k for overclocking.
Then, the ASRock Motherboard was chose because it has PCIe 3.0 for next generation video cards like the upcoming Radeon 7000 series and GTX 600 series video cards.
Finally, 8GB of DDR3 1600 and a 750GB 7200 rpm hard drive were included for ample RAM and storage.
I believe this build is better than the previous.

However, if you can hold out a few months, Ivy Bridge Processors will come and so will the new graphics. Previous gen parts will become cheaper.

If you are not overclocking, go with an i5 2400 and save $30 for retirement or buy 1/15 of an apple Stock.  

Personally, i would get the SSD. SERIOUSLY. GET IT...
