Too big for my case?

[Saturn891]

I'd like to buy the Scythe Samurai ZZ heatsink for my Gigabyte GA-8I848P-G motherboard (socket 478). Is the heatsink too big for my case?

Note, the red button with red and white wires is connected to reset pins. Because the reset button of my case doesn't work.

I've installed the heatsink, no problem anyway!
