Man, that is very cheap.
I'd go for the P182 just because it's bigger, but that was a personal thing because I needed the extra drive space.
Both seem good for quiet computing, as referenced by SilentPCReview's reviews of both cases.
The Solo does have a hard drive isolation system in place, where the P182 relies on the standard screw-it-onto-the-cage approach, albeit with silicone rings around the screws. However, I believe the Solo's system does deteriorate over time, as my friend's system appears to be suffering from it. The bands eventually get stretched to the point where they drop down onto another HD or onto the bottom of the case.
Other than that, they're both good cases. Either one should accommodate that part list well, but the P182 will keep the PSU away from the incredible heat generating power of the Q6600.
EDIT:
Wouldn't a stock HSF be spinning like mad to cool the Q6600? That negates a quiet system build pretty easily. Unless you won't overclock, but even then.. I'm not sure. Someone who actually has one can step in here for you.
If you want a quiet system, you also will want to replace the case fans. The included Antec Tri-Cools (on the P182, not sure if the same ones are on the Solo) are decent, but loud even on low. Get some Scythe S-FLEX, Scythe Slipstream, Nexus, Noctua or Yate Loons to replace them with and undervolt.
No idea on how noisy that PSU is though.
