I've noticed that sometimes the NewEgg customer reviews are not actually reviews. Rather, someone will just post a "review" to respond to another reviewer. Furthermore, sometimes a comment is so incredibly ignorant that it needs to go away. I've seen comments with things like "1 out of 116 people found this helpful." An example of this would be the guy who took an egg off his monitor because his desk was too small for it and the keyboard.
Both of these things take away from the value of customer reviews. I suggest 1) reviews stop counting (egg-wise) and the post is greyed out when the "not helpful" to "helpful" ratio is rediculous, say 10-1. 2) Allow for more discussion on a piece of hardware aside from the reviews. This helps people resist the urge to write reviews when they just want to say something to/about another user, and it lets people who aren't/can't review the hardware talk about it. Another option might be a "nuetral" rating. Instead of rating from 1-5, you choose to not have your vote added to the total.
The first is a no-brainer and not too difficult. The second suggestion is more difficult, but might be worth considering in some form.
