Can I throw all these parts in a case and it will work?

The time to ask a question is BEFORE you buy, when you can change things; not after.

In this case, your build won't work without a discrete graphics card. The 2550K does not have integrated graphics.

Ram vendors will not guarantee proper operation of ram sticks that are not part of a single kit that they can test together.
Your purchase of two 8gb kits is likely to work ok, but you paid more than you would have had you bought the same ram in a 16gb kit.

In my opinion, the H100 is over priced, noisy, and complicated.
With a good cooling case you could have spent less on a good air cooler that is easier to install, quieter, and just as effective.

And like the other guy said.. Id grab an air cooler such as this one

Thank you geofelt. I know I ask this b4 i buy, but I've been going over thios for the last month. I am aware the 2550k doesnt have on-board video, so thats fine. I'm getting a card. I really hope the ram works, and the H100 is really good for the money. I would like my temps below 20c and I MIGHT get an additional H80 just for that  

stevandv, I cant change it now and I'm happy with the cooler. I was just worried about the 1) PSU, 2) RAM and 3) Case  

did you get a vid card?

20c is 68f.

You will need to keep your room at 50f or 10c if you hope to keep the cpu at 20c. Not realistic.

The temperature at which your cpu will throttle is close to 95c.
If you are seeling record level overclocks, then the H100 might be good.
If noise is an issue, then the H100 might not be for you.

If you want the best cooling, look at the Noctua NH-D14 which even costs less:

Actually, you would be fine with a $30 cooler like the cm hyper 212 or Xigmatek gaia.

Spend your money more wisely on a ssd or better graphics card.

20c is a target that will take effort to reach. Why?

The laws of thermodynamics.

How could you reach 20c?

1. Your computer is air-cooled and in a room where the temperature is enough below 20c so that when your system is operating, the system only reaches 20c.

2. Water cooling which utilizes some sort of water chilling mechanism that brings the water temperature below 20c. Most water coolers I have seen do not implement a chiller like this; rather, they air-cool the water through a heat sink.

3. Dry Ice, liquid nitrogen, or liquid helium.

HTH

Cases are a personal thing. If you love it, buy it.
I think there are others that perform just as well at half the cost.
For example, the LIAN LI Lancool PC-K58W for $80

For a psu, stick with known quality brands. Antec, Corsair, Seasonic, XFX, and PC P&C.
An iffy psu is the last place to economize. A 650w psu will run a GTX580, a 7970, and probably the upcoming GTX680.
Here is a good Antec EarthWatts EA-650 GREEN 650W unit for $60 after rebate:

ok ill return the 800w psu for a 750w. i am planning to x3 sli GTX 680's by 2014.

I think you are a bit crazy considering triple sli GTX680, but then, arent we all 

It looks like the GTX680 will need only two 6 pin pcie power connectors. Each can deliver 75w, and the slot can deliver 75w, giving a max load for each card of 225w. Add in 150w or so for the rest of the sustem, and it looks to me like you will need a 850w psu to implement that plan.

The flagship Nvidia card is yet to be disclosed, but by 2014, that, or something like it will probably be the preferred upgrade path for triple monitor gaming.

Haha I'm not using x3 monitors. I was thinking x3 monitors 3D!!! by June, but IDK if that is existent. Oh, and the PSU I'm thinking of actually going to 1000w but not Cooler Master. I called Newegg, there so awesome that they canceled it in 23 seconds. God I love Newegg, but yea I will most likely buy a Corsair 1000w, or 1000w XFX!
