Competitively priced? Hmmm, a 24" Imac is $2300 canadian. This is with only a dual core, only 2 gigs of mem, and only 1 500 gig drive and the vid card is only a 8800 gs, not a gt but just a gs.
iMacs aren't the comparison point (since they also come with monitors). hackintoshes compare to either mac minis or mac pros. The mac pro is competitively priced for what it is (as long as you don't buy additional RAM or disk from Apple). However, most people don't need or want octo-core xeons. You can build a very fast quad core hack with good video for under $1000. You can buy a capable hack (low end) for less than $500 if you shop deals and carefully pick parts.
However, it's pretty hard to piece together a dual CPU system with a pair of quad core CPUs (typically xeons) running FB-DIMM ECC memory for less than what Apple wants for a Mac Pro. If you really need/want 8 cores, get a Mac Pro. If you want to save money, can deal with steep learning curves, and only need quad core (or better video options than a mini/iMac), a hackintosh may be for you.
(and if you buy an iMac, have fun 3 years from now when the computer is obsolete, but still embedded in a 24" 1920x1200 display).
