-use a good case like a antec 302. The case you have is crap
-don't use a crappy power supply. I'd suggest a fx 550w for 59.99 after MIR at us.ncix
-I'd suggest getting some patriot viper 3 1600mhz for 25.99 after MIR at newegg
-b75 won't let you overclock. Get something like a z77 extreme4
-il you are getting a gtx 670, get a msi power edition
im buying the graphics card next month.Thats why i need to knowif everythiing is all right before that time comes. But I guess if I have to ill set it up on a test bench before I get the right casing . Any case will do I just want it to fit so I can use it not look at it.
As was stated before, if you are going to get a 3570K then you should get a Z77 series motherboard that will let you overclock the chip. The K at the end marks an "unlocked" chip that will be open for overclocking. If you don't plan on overclocking then saving a few bucks by going i5-3450 is reasonable.
If you do plan on overclocking you should include an aftermarket CPU cooler, no need to get fancy here, a 35$ CoolerMaster 212 EVO will do just fine (Have my 3570K running at 4.5 GHz using one).
The case is really up to you, whatever looks ok and fits your budget.
I totally agree with you on going balls out on the GPU (GTX670 love it!) as it is the most important part of a gaming PC.
The power supply is really not a good place to try and save money. You also have a decision to make, do you go for a ~550W power supply or do you crank that up to ~750W for the glorious day when you plop a second GTX670 in there SLI.
Memory is fine although most people would recommend going for 1600mHz memory modules, not convinced it makes that big a difference but i don't think they are that much more expensive. From personal experience i would recommend LOW PROFILE memory cause nothing is more frustrating than not being able to mount your aftermarket CPU cooler because the memory modules are too high. An example of low profile memory: GSKILL ARES series.
yep. all you need to do is plug your modem or whatever to a adaptor into a wall, plug another adaptor somewhere else in the house where you want internet, and then connect a ethernet cable to the adaptor to get internet.
