New to forum. Start off w/easy question

[brianw1967]

Hello all, this is my first post and first build. I?d like to say thank you for all the valuable information I have leeched from this site so far. As I said earlier I have decided to build my own computer and have a few questions pre-build. First I will start off by listing all parts I have and am in the process of installing.
1 anatec 900 case
2 Gigabyte GA-P35-DS4 rev 2.1
3 2-GB OCZ High Performance memory
4 1 XFX 8600 GeForce car
5 anatec Neo HE 380w PSU
6 1 ASUS DRW-2014L1T DVD-R (Sata)
7 1 West Digital 320 MB HDD (Sata) Operating System
8 1 West Digital 750 MB HDD (Sata) Storage
9 Intel E8400 Chip (The only component I do not have yet, It is on order from NCIX)
10 I plan on using vista ultimate as an OS

I started assembly today as my 8400 chip should be here mid week or so. I installed the MoBo w/the standoff and screws. My question is: the anatec case came w/ a bunch of non-metallic washer. Are they supposed to go between the screws and the motherboard, or the motherboard and the standoffs? Or are they not for the motherboard at all. I have searched the user manual on the motherboard and the case to no avail.

don't even bother to use those cardboard washers. Modern ATX mobos are intended to be grounded to the case via the mouting screws and pads.

Definitely do not use them. They are NOT needed. And welcome!

Also, I'd take the MB out of the case, as almost all problems with not-quite-fully mounting the Intel 4-pin style CPU cooler come from trying to mount the cooler with the MB already in the case. Check out this quick guide: http://www.tomshardware.com/fo...part-assembly#t1184072

The mounting hole ground pads are intended to serve as discretionary chassis ground points strictly for ESD and EMC purposes, primarily the latter. And no, industry standard motherboards intended for mass-market typically do not incorporate design assumptions about whether the mounting hardware will be metal, plastic, or bubble gum. The question of whether implementing the mounting points as chassis grounds would contribute to or detract from EMC is left to the sole discretion of the system designer to determine by actually testing their designs for EMC.
