Question about setting up a computer

I was looking at some sites on how to set up a computer and it says you need to ground your self from static electricity??? Is that true

Also i was planning on buying a Thermaltake SpinQ, Would anyone know if it would fit a CoolerMaster HAF 922???

As long as your feet or the computer are touching the floor, its grounded

Like someone else said, make sure your feet are touching the floor, and just touch a metal part of the case before you handle the components. I've built over 100 computers and I've never had a problem with a static discharge.
