PSU: you think that after I have 6 HDD in there and the rest, my build wont exceed 325W?
Maybe once you've got all the hard drives in, but it still won't be anywhere near that PSU's limits. The only time HDD's use a lot of wattage is during spin up, where they can use as much as 25W each. the rest of the time, it's usually between 8-12 watts each, depending on what's happening. During that spin-up time, the rest of the rig isn't going to be maxed out...not even close. So let's do the math once it gets up and running:
6x HDD = ~70-75W if they're all reading/writing...which is unlikely.
GTX 460 1GB = 108W, more for the overclocked one...we'll say 125W, when it's maxed out. Again, unlikely unless you're really crunching on something.
1090T = 125W, maxed out. Again, unlikely unless you're doing some hardcore editing.
We'll make a conservative number and say 60W to run the fans and chipset and whatnot. That's a high estimate.
So, in the very unlikely scenario that all of that is running maxed out, using conservative numbers, that's still only 385 watts, or around 325 with just the single hard drive.
If you want room to add a monster GPU or something in later on, you may want to go with a ~650W model instead. Otherwise this one is great, I think. There are some good quality 500W units for lower prices, but none as good as this.
If you want a more powerful and still very good unit, this would be a good choice...still an excellent performer, and actually a bit cheaper:

Review on the 750W version (the 650w is the same platform)
RAM: what is cas7 or cas9?
CAS latency is the number of clock cycles it takes the RAM to return information to the CPU after it has been requested. When you see numbers relating to RAM like, for exampple, 7-8-7-24, CAS latency is the first one, and the most important. Basically, it's how efficient the RAM is. Thus, DDR3-2000 Cas9 is 25% faster at returning results than DDR3-1600 Cas9, while DDR3-1600 Cas7 is roughly 20% faster. Only 5% difference. (That's oversimplifying things a bit, but you get the idea)
With AMD chips, lower latency is preferable to high clock speed, since the CPU's memory controller has issues with high speeds. (The highest official DDR3 spec is 1333, haha)
If you want a cheaper kit, this should do well and is a good $75 cheaper :

MOBO:I already have windows 7 pro with a key I won't need the bundle so I can probably get the mobo for cheaper.
Ah..yep, you can.

GPU: Would I really benefit from the overclocked GPU?
Unless you have some epic plugins for photoshop, probably not a
whole lot, unless premiere finally allows 460's to run. However, the build quality on that card is excellent, and the cooler is significantly quieter.
If you want a regular one, $25 cheaper, this is a good choice:

PS: In several cases the parts are cheaper in stores around me
That'll definitely help.
