[QUOTE="trivialrage"]is it really worth upgrading when your only gonna get an extra .5 gig?plimpoperp

Personally I would rather stick with 3.5gig then goes through all the hassle of backing up and reinstalling just to get 4gig

So long as your case and motherboard are of the same form factor eg: ATX then yes there will be holes.
If your concerned about your motherboard then for your own peace of mind use a static bag. But otherwise just do what the other guy said ground yourself.
No harddrives dont come with cables the motherboard has them.
And if your cpu is new it should have a thermal pad/paste already on the heatsink.
