^+1 The Hyper 212+ is a great choice, the only thing is, its stock fan can run a bit loud, so if you are bothered by noise just change the fans. Scythe S-Flex and Slipstreams are good. They aren't as high RPM, but they do the job. Actually the highest RPM Slipstream moves lots of air and is somewhat loud 30-something dBa if i remember correctly, but still is a million times quieter (Exaggeration!)
V8 is fine, well I use it on my 955 so i don't know, it's pretty cool, then again the max temp of a 955 vs i7 930 is pretty much way different. I'd recommend the V8 only if your getting a good bargain on it. The best of your choices would be the NH-D14, but that has many problems with clearance of ram. The best I'd say would be the Venomous X-RT. or Venomous X
I have the Noctua D-14 and yes it is quiet and fits on that board ( same as I have) just watch for clearance of ram.. I have mushkin redlines and they fit under it.. keep in mind the d-14 hangs over 4 ram slots.. yes it is that gigantic! but temps are wonderful.. it got me to 4.41 and still get 75C under prime load so with a small oc, the fans are virtually inaudible.. my ocz stealth xtreme psu is the loudest thing in my pc.. go figure lol
The D-14 is a great cooler no question but it wouldn't be the best choice for someone with an Antec 300.
It would take up alot of real estate in the case which isn't all that roomy to begin with.
If you want better then what i've already suggested go with TR Venomous X or one of the Prolimatech's either the Megahalems or Armageddon.
Plus you have won half the battle as far as pairing a cooler with ram.
Your ram choice is excellent for clearance as it's only 33mm tall and any cooler you choose will have basically no installation issues.
I wouldn't spend more then $50 if you don't plan on overclocking much more.
Scythe Mugen 2 rev B @$40
Corsair A70 @$50
Any of those coolers will do quite fine even to 3.6Ghz .
