I am building a "rack" for some computer servers. The basic structure
for the rack is the IKEA GORM shelving unit
http://www.ikea.com/us/en/catalog/products/S59850857

I have the following equipment to place on the rack
o two servers, each is a rectangular box about 6"x16"x18" (WxDxH),
weighing about 20 lbs each.
o LCD monitor about 17"x17"x6" (WxDxH) weighing about 10 lbs.
o one printer, a rectangular box about 14"x12"x10" (WxDxH)
weighing 20 lbs.
o 4-5 stacks of standard letter paper (each is about 2 lbs) and
miscellaneous office supplies

My main requirement is that this shelf should not topple.

Your problem has nothing to do with physics/statics.
Just forget the IKEA unit and look at something like
randmh.com/chrome-wire-mobile-shelving-unit-m836ch/wire-shelf-carts/
instead. I've been very happy with my three similar units,
http://www.forkosh.com/jfrack1.jpg
illustrates one of them.
Very sturdy, impossible to topple, supports up to 1200 lbs,
and the casters make access to rear cabling very easy after the
unit is against the wall. A bit pricier, but worth every penny.
