First time building a comp. Need help confirming compatibility/quality

Why 1366?

Your Windows Home Primium is the 64 bit version correct?
Is there a reason you are going with the 1366 socket , you can save a lot of money going with the 1155 socket system and get a much better computer.

A couple things:

- Don't get a 1366 system at this point - it'll be obsolete in about a year when LGA 2011 is fully out - you want at least an 1155 system or better.

- Get the low-profile Vengeance RAM, those tall heat sinks could cause any damage to any third party fans you could install on your system.

- Go with a Corsair, Seasonic, or PC Power & Cooling PSU over Antec any day of the week.

- And what case are you using? Are you using your existing case, or are you planning on buying something different?

Zalman fan for $99? Really? For that price why not go with a Noctua D14 or Corsair H100?

There should be a link to the computer case I am buying in my post. Just in case, it is the "HAF X full tower".

Awesome! Thank you so much for the advice. I'll start looking into that. As for the case, it is only a $10 difference but I have amazon prime AKA free 2-day shipping. Not a deal breaker or anything, I would just prefer to buy on amazon is all. (So i can get everything shipped together and whatnot)

So I updated my build. Anything that is not mentioned here is the same as my original post.

As for the power supply, I found a different one that is made by Corsair. Could someone please let me know if it is compatible with my build (and compatible with future upgrades like crossfire [I know I may need something more powerful for crossfire])

As for the RAM, I don't plan on installing 3'rd party fans (or water cooling) for a while. I will probably go for water cooling and they seem to be fairly small and I probably won't need to change the RAM (hopefully!).

*And the OS is indeed windows 7 home premium (64-bit)*.

Thanks for all the advice and please let me know how my updated build looks. I really don't want to rush into a purchase of something that won't work so I GREATLY appreciate your feedback.

The 750w should do for crossfire but if you found an 850w that wasn't a lot more it would give you some extra power to spare just in case , but that is only if you crossfire. The reason I say that is that you chose a high end AMD card and it does require more power.
The Half-X is indeed a full tower case and there is an enormouse amount of room and featires with that case. I have one and I absolutly love it.

I'll keep that in mind for when I'm ready to crossfire. Thanks for the advice.
