Which would you recommend, B25S or B10?
I really could not say. I liked the B25S for its cool features and good looks despite its oddities and can make a system in there that is quiet enough for me, but I don't know that it would be my first choice. My guess is that the B10 might be quieter because of the door, but it could have other quirks that need to be dealt with, too.
I don't particularly like Lian Li, it's just that it seemed to be the Roll's Royce of chassis, and since I can afford it I thought i'd go for it. I don't really care whether it's aluminum or not either, it's just that I think aluminum has better heat dissipation than other materials. But in the end I just care about the result (cooling and silence), so whether it's Lian Li or not, or aluminum or not doesn't matter.
OK. I'm not big on the idea of a "luxury" case that has lots of features -- if I will never use them. To me, generally, function should follow form; beautiful is as beautiful does.
When I think about all the cases that have come through here over the past couple of years, the one that stands out most -- from a functional, silent-featured viewpoint -- is the NZXT H2 http://www.silentpcreview.com/nzxt-h2
. Like the Fractal and many other "silent" oriented case, it is a P180 takeoff, but it's done very well. Its built quality is solid -- I prefer it to the Fractals, whose mechanicals never seem quite solid enough to me -- the overall design and features are excellent, it's practical. It falls flat in not have open enough intake vents -- but that can be fixed somewhat (as shown in the mod page in that review). Once modified, as long as you don't shove a really hot video card in there, it will work very well. In fact, I am using that modified H2 sample to house my next main PC -- still haven't finished loading all the software, so until that's done, I'm still on this reliable old Win XP / C2D machine. The primary components for the new rig are 2600K, 8G RAM, Radeon HD6850, SSD, and WD Green 2TB. It's silent, really fast & powerful, & cool.
I haven't really made my mind about the gpu. I am not a gamer, though I'd like to occasionally be able to play demanding games if I want to. I will buy the 3930k, which doesn't have its own integrated gpu so I will need one relatively good for all the graphics calculation. I have a large screen (27'',1920*1080). I want a gpu that is good enough to match the goodness of the rest of my future configuration, yet not overly expensive since I don't play regularly. I would also like it to be able to help the cpu for demanding calculations, since I sometimes (more often times than playing) do mathematical (mathematica, maple, ...) computations. Finally, I would like it to be as silent as possible. As a comparison, my current one doesn't make any sound, it's fanless. It's the 7600gs from nvidia if I remember correctly. With this description in mind, do you have a gpu to recommend to me ?
The most powerful fanless card is probably the Powercolor SCS3 AX6850 Radeon HD 6850. Gigabyte GV-R677SL-1GD Radeon HD 6770 is also a decent bet. There seem to be far fewer higher end fanless nVidia cards, though there is always the option to mod a fan cooled model w/ a passive aftermarket cooler. Re- GPU support for general computation -- all current model AMD GPUs should support OpenCL; nVidia has CUDA.
