I have 3 different computers and building a 4th, why?
Each one has a pacific purpose.
 
One is my main computer that I do searching the web, email, banking, SETI at Home, and play older games.
It's a 6 year old X58 motherboard (Asus Sabertooth, it sucks and will be replaced with another X58 motherboard this week). Asus customer support sucks.
It has a i7 980X CPU (6 core) with 24 GB ram and a EVGA 1050 Ti GPU.
 
My other computer is a X58 Asus P6t Deluxe Version 2, love this motherboard.
This has a i7 975X (4 core), 12 GB ram a small ssd drive and a 6 Tb Seagate hard drive with 2 EVGA 1050 Ti GPU.
 
I run Plex media server, DVDFAB (a video ripper and converter) and SETI at home.
DVDFAB uses the cuda cores for high speed translation of video formats so I have to turn off SETI as it uses the cuda cores too.
With 1 EVGA 1050 Ti DVDFAB does up to 500 frames per second, with 2 it does up to 1400 frames per second.
 
My monster is built around a Cosmos II case, i7 6980x (10 core CPU), 4 Corsair Dominator Platinum 3000 MHz 16 GB (32 total) (so I can use the 4 channel memory), EVGA 1080 Hybrid GPU, EVGA 1080 super clocked GPU, EVGA X99 Classified motherboard that has a 4 core Sound Blaster GPU.
A small ssd drive for OS and a 1 Tb Seagate barracuda hard drive.
I plan to add 2 more 1080's GPU's as the motherboard supports 4.
 
Although this would be a great video editing machine I do not use it for that.
I use it for SETI at Home only.
 
Lastly, the new one I'm building has a EVGA case (DG-85) that I suggest you don't buy as it has no provision for a DVD drive. You have to buy a external USB one.
 
I plan to replace my P6T with this one.
So far no cpu, ram, gpu.
So what are you using your new computer for?
 
I suggest you buy from EVGA as there customer service is way above anyone else.
 
In conclusion, buy motherboards, video cards from EVGA.
CPU, RAM, Cases from someone else.

Those MOBO suppliers listed by MSim (sorry just my experience on support);  EVGA may cost more for some mix of features, but if some thing is not quite right and it fails in the warranty time...it is addressed immediately.   
[I have never had those 3  mfg address my mobo issues period; just had to purchase a new MOBO.]

I never had a motherboard mess up on me. Every day of the week i would take a motherboard that has premium features over paying more for less. What's it say when most places that sell custom built system choose ASUS, GIGABYTE or MSI motherboards for the majority of the systems they sell. 
 
EVGA uses outdated audio chip 1150 (ASUS, GIGABYTE and MSI use realtek latest audio chip S1220)
EVGA uses basic realtek audio software
EVGA doesn't give you software to overclock and control system fans from the desktop
EVGA doesn't give you water flow header or RGB Headers
 
I have no problems recommending or going with evga when it comes to graphics cards or power supplies.
