I know this isn't really the right section but it will be cool :) I promise.
Okay so i'm going to be reasonable, Having 4x7970 in Crossfire isn't a dream PC.... It's an ear bleeder xD My style of a dream PC is one that delivers performance and doesn't wake up the neighbors. So this is my dream PC & accessories.
General
Case: Antec DF-85
Motherboard: G1.Assassin 2
Processor: Intel i7-3960X
Graphics cards: Dual ASUS MARS II (SLI Enabled)
Memory: 4x8GB Patriot Gamer 2 series 1866MHz
Power supply: Antec HCG-900
Accessories
Keyboard: Cyborg V.7
Mouse: Cyborg R.A.T 9
Gamepad: Cyborg V.5 Rumble Pad
Headset: Turtle Beach Ear Force Z6A
Reason of choice Case:
I have chosen the Antec DF-85 because of its big space. It could easily fit all of my components in with no hassle. It looks stylish and the features are awesome. I love the fan trays at the front with the air filters making cleaning your fans alot less messy.
Motherboard:
The G1.assassin 2 is just lush. It looks amazing and is a right show off. The little pistol and the sniper barrel is just epic. The main reason is the looks

But the 4 channels of memory and support for LGA 2011 are other reasons. It comes with a new style of BIOS called 3-D and is very handy. I may elaborate in the future.
Processor:
As far as i'm aware of the Intel i7-3960X is the most powerful processor that Intel provide for Desktop computer (Please don't rage if i'm wrong just correct me

) so the reason is clear on this one :).
Graphics Cards:
Having 4 Gpu's is quite immense itself but having one of the worlds fastest ones is just so cool. The reason I choose the ASUS Mars II is because It will be able to play any game at ultra with a very high resolution on three screens. Maybe not so much if there was only one but having two running in SLI i'm sure it would breeze that with at least 60+ FPS steady.
RAM/Memory:
Very high speed Memory and reliable. Having 32GB of RAM is more than enough for most people and is very useful if your Rendering or running a Dedicated server for games. You cant go wrong with this choice.
Power Supply:
I'm pretty sure that having 900Watts is enough for my Dream PC and ill double check in part two because I haven't looked at the requirements for my CPU and GPU. But the Antec HCG-900 is a very quiet Power supply considering the power it gives off and would fit right in with my case.
My conclusion is that my Dream PC could be improved but it is my personal favorite. The looks are great, The performance is outstanding and the overall result would be gob smacking. Thanks for reading my review/build whatever you want to call it :).
