I am putting together a desktop first time & need help.

I am looking for a Motherboard with minimum of 4 PCIe x16 slots & should would work with Intel I-7 2600K Processor.

As long as all 4 slots run at minimum 8X speed is fine.

Also need suggestions for a GOOD Brand RAM + PSU & Case.

Budget is Flexible & need Reliable system.

the above link seems to have what you requested 4 PCIex16 2 at 16x speed and 2 at 8x, with an LGA1155 (Intel i7 2600k)

While people have different opinions on RAM, my friend purchased corsair and he RECIEVES a lifetime gaurantee.

I haven't replaced many PSU or cases so I can't comment on them.I have had a few Kingston sticks fail on me overnight, so it is not exactly the most reliable brand of RAM.
If you are looking to build a high-end system with that motherboard and processor, I would suggest some high-end RAM by Crucial Ballistix, G.Skill Ripjaws, Corsair Vengeance/XMS2, PNY XLR, Patriot Gamer 2, and Mushkin Enhanced. G.Skill Ripjaws 4GB is now selling for $29.99 on newegg:

You probably want to ADD a graphics card too, maybe even in an SLI or CF CONFIGURATION, so I would get a 1000W PSU.
Here is a list of the brands you should and should not buy:

If there are reviews available online for the product, MAKE sure to read them-there is nothing like first-hand customer input.


As for the chassis, you might want to look at some of the featured ones on Anandtech:
