make sure you get the 64 bit vista with 6 gb of ram. I am also planning to build a core i7 system that is very similar. I know right now you can get a gigabite motherboard for the same price as the p6t that you want to get, but it comes as a combo with the gpu you want to get, and you save 30 dollars, so maybe you should switch the mobos. Also im not sure what you are doing with your pc, but if you are gaming it might be worth it to sli 2 gtx 260 core 216 and just get a thermaltake 850w psu. It is on sale right now for like 110 if you buy the combo with the core i7 920, so not a bad deal and it supports sli.
Will this be hard to build by myself, especially if I've never built a computer before? I'm not really considered with how hard it will be.. I just don't want to screw it up. Should I just seek professional help?
Looks great! I just built mine yesterday and it's running sweet! It was my first build too and I was very nervous to say the least. Not knowing what to expect, it being my first and all. But I dove in and prepped the case and installed the hardware. Connected the pwr to the board DVD and HD, also one to the HD4850 gpu. Got everything wired and tucked neatly away then it was time to push pwr... To my surprise everything lit up and purred like a kitten, er I mean mustang!
I got worried because in post I would see it flash saying no HD detected. But, it let me install Vista no problem and even boot right into it. I did a lot of online research and it seems that is the marvel ide controller looking for an ide drive. Mine is SATA so I guess that makes sense. Someone said to disable the IDE controller in BIOS but just haven't gotten around to it.
After installing all the drivers and apps on the ASUS DVD the system started making the beep that you get in IE when you click to navigate to a web page every 10 sec or so... Drove me nuts until I read here that the RAID controller or something, so I uninstalled it since I dont have a raid set up anyway - it stopped. The only other issue I has so far, once I pluged in my new Logitech Illuminated Keyboard, start up would get stuck at the ASUS splash screen for over 2 minutes. Once it FINALLY booted into Vista it worked fine. Hope Logitech or ASUS sends a fix for that soon, love this keyboard.
Other than that, it was quite easy even for a first build. Good luck and enjoy! Just pay attention and read up on other people's builds and you should be fine.
