Mild 2400 Overclock on "Emergency" build

I just ordered parts from newegg to replace my old PC, which died. :fou:  It was sooner than I expected (I had been planning a ~$700 build around a bulldozer, but I got a $600 build around a locked Sandy Bridge chip.

My parts:

Windows 7 Home Premium

i5-2400 3.1 Ghz Sandy Bridge

AS Rock H61M-VS

Muskhkin 4GB DDR-1333

500 GB Seagate SATA 2 Hard drive

LG DVD burner

Corsair CX430W

HIS HD 6850 1GB

Roswill R-102 Micro ATX Minitower

Blue 120MM Fan

generic 80mm fan to replace shroud, if necessary (not purchased, just lying around, I have at least 4 that can be cannibalized from hulks of old builds)
A generic usb keyboard & mouse I already have will be used with this computer

My existing monitor is a 21.5" Acer 1680x1050 model, and I'll use that for now, Might occasionally hook it up to the 42" 1080p TV.

I know the 2400 is limited in overclocking, but here's my questions:
Can I still up the limited +4 Bins on an H61 barebones mobo?

the Extreme PSU calculator, with 100% TDP, 90% System Load and 20% Capacitor aging suggests 380W for a 3.5 GHz Overclock, and 393W for 3.6 overclock, so my 430W PSU seems like it should be able to handle this, assuming its a solid and stable OC, for at least 2 years of regular use.

Many will wonder if the 6850 will fit in this small case. the 6850 is 9.1 inches long, which is shorter than the 9.6" motherboard. It should fit, but might block one of the internal hard drive slots. Not serious, as I only plan to use at most 2 of the 4 spaces anyway (eventually add an SSD). Also, several of the feedback posts mention squeezing in a 4850 back in 2008/09 as well

the RAM and Video card I'll be mostly leaving alone, though can anyone suggest timing changes for that mushkin ram?

Anyone have any other suggestions? Parts have already shipped

Should I repost this in the General Overclocking board?

You will likely be the first to have an H61 mainboard on these forums ... you'll have to tell us whether you can do it or not.

As for timing changes for the RAM ... leave them at 9-9-9-24. Your system doesn't need lower timings, and you won't be able to overclock the speed on that chipset.

Good luck!

IF this mobo can overclock you might get +6 bclock which would be 6x31= 186Mhz.
