Motherboard is shorter than spacer base??

[Warpspasm]

I'm in the middle of building my new rig. I have the following:

Motherboard: GIGABYTE GA-P35-DS3L
CPU: INTEL Core 2 Duo E4500
Video: VGA EVGA 512-P3-N802-A1 8800GT 512M
Mem: 2GB CRUCIAL BL2KIT12864AA804
Power: OCZ GameXStream OCZ700GXSSLI 700W
Cooler: ROSEWILL RCX-Z775
Case: Coolmaster 830 EVO (if you think this case is big, trust me it's still bigger than you think)

I got the case out and put the spacers in the nifty slide-out motherboard tray where it said they should go for an ATX motherboard. I laid the motherboard on the spacers and they lined up fine. Except, there are three spacers left over! They are the ones that would go along the trailing edge of the mobo (away from the ports on the back of the pc). I mean, the motherboard seems stable and all, but why the heck are there some spacers left. It's as if my motherboard should have been a few inches bigger. What's up with that?

BTW...any thoughts on this build? Too late to change it now, but I'd be interested in hearing feedback and any tips that can be passed along.

Most cases, are sent, with extra, stand-offs..How many, does your M/B use?..(9) is std..

Only use the exact number of spacers required by the mobo, if you use too many or too few, you're likely to run into problems, can cause a short.

Yeah, I decided to pull them. I can't see any reason to leave them there.

So whatdaya think? Will this be a decent gaming system? (assuming it all runs when I put it together)

Haven't used that case, but if it came with standoffs you need to USE them. Your motherboard will short out on the tray. Hate to see fry a new MB .

 

[Warpspasm]

The problem is, the extra standoffs are a few inches away from even touching the motherboard. The board is on most of the standoffs and isn't touching the motherboard tray. I guess some ATX boards are larger than others?

I think those extra standoffs are for E-ATX boards. Newegg lists all three motherboard form factors (m-ATX, ATX, E-ATX) as compatible with the case.

m-ATX boards are normally 9.6"x9.6"
ATX boards are normally 12"x9.6"
E-ATX boards appear to be 12"x13" or so.

I just looked at the Gigabyte site for specs and it says:
ATX form factor, 305 x 210mm

That would be 12.01" X 8.27". I'm at work now, so I can't check it, but that might make it about an inch or so shorter than what you're listing as the standard size. That is probably about how far off the last standoffs are.
