LIAN LI PC-65B cooling

No you cannot replace these fans with bigger ones without modding. This case is somewhat compact (at least compared to my p180) but it manages to move air fairly well assuming you manage your cables.
 
I guess you could do that but then you lose the window, and from the ops post it doesn't seem like he wants to mod. But if the window isn't a factor then he can do as he wills.
 
He can, but from the looks of it only on the top blow hole, unless he is willing to put it on the outside of his rear exhaust which is just a bad idea in general.
- The two front intake fans are placed tightly next to the hdd cage and the rear exhaust is immediately under the PSU and after eying it it doesn't look like it will fit.
If he decides to do that then he will have to adjust fan speeds and play around with things, just because you have more air moving around in your case doesn't necessarily mean your going to get lower temperatures.
 
The Silverstone FN82 and FN83 are designed to fit into the 80mm screw pattern but have 92mm blades, so they will probably fit without any modding.
I have used the FN82, it was installed on the side panel of my old case. The side panel was a pre-mod so the only upgrade to the 80mm fan was this Silverstone. It worked well (still does, but I have retired that case).

Or he could get it here and just add $10 for the window, if he's really set on the window. It would wind up costing just a bit more than if he got the PC-65 at Newegg.

That's exactly what I did with my last build. The PC-7 and the PC-65 are very similar designs and I think the largest difference is the lack of a motherboard tray in the PC-7. For me personally I made the tradeoff for 120mm fans instead of the motherboard tray. To each his own though.
 
The case cools pretty well. It has a blowhole which helps. You can use those 120mm -> 80mm adapters, but if you keep the HDD cage installed, you won't be able to use the adapters for the intake fans.

The airflow is pretty good. You'd probably run the intake fans at the same speed and play around with the exhaust and blowhole speeds to get the airflow where you want it. This of course only matters if you get a fan controller. If you really want to use 120mm fans, I'd go with a different case. Plenty of great 120mm fan cases out there. Spare yourself the hassle.

Are you set on a big case? The A05b is the same width and depth as the PC-65b, but shorter. It's about as small as a case can be and still allow ATX components. The PSU is below the HDD cage. Airflow is reversed, and it uses two 120mm fans. The only cooling issue is that hot air gets trapped in the top rear corner, so you'd need a blowhole, a slot cooler, or a video card with an exhaust enclosure.
