Good call on the Silverstone; that's exactly the kind of thing I'm looking for. The only complaint I have is the stupid vent over the video card area, but that's nothing some hot glue and foam-core board won't correct.

Further suggestions are still welcome!

Looking for small, high-quality case

I'm looking for a relatively small case with excellent build quality and appearance. As far as size is concerned, I'm mostly interested in something along the lines of the Antec NSK 3480; just barely big enough to hold a mATX motherboard, 120mm fan, and possibly a full-sized power supply (although a...

You can use that in a computer very easily. The power switch in any ATX computer is just a momentary switch, which is exactly what you've bought. You'll just want to hook the power switch leads inside your case up to that switch instead of the built-in switch. I can't really counsel you on mounting ...

When I mentioned trying an 80mm fan, I didn't mean one of those plastic funnels - pretty much the only reason to install a 60mm is if an 80mm wouldn't fit on the back panel, so I assumed it was pretty tight in there. No, what you'd have to do is construct a duct out of heavy card stock or foam-core ...

Normally, this is a bad idea. That's because normally , adding just one extra 120mm fan to the case and running it at very low speed will result in lower total noise level than letting the PSU fan handle all the ventilation duties. However, you've got a bit of a special situation, with those 60mm fa...

Heat spreaders aren't really intended to reduce RAM temperatures, and are completely unneccessary on DDR RAM of any variety, because the heat is already spread evenly over the chips.

The problem you're running into is that a modern PSU won't provide power on anything but the standby rails unless it's plugged into a motherboard via the main ATX connector. You can trick the PSU and bypass the issue by shorting the green wire in the ATX block to any of the black wires.

A 450 watt power supply is more than adequate for a system like this. You would actually be very safe with only 300 watts, but most of the really quiet choices lately have been higher wattage. I'd actually suggest an Enermax Modu82+ 425.

Definitely the Solo. The Cooler Master cases are basically frames with mesh for body panels, which means they won't reduce sound even slightly, and probably don't even have great airflow - they have lots of airflow, but because there's no predictable path it'll require a large number of fans to ensu...

Notice that the system requirements call for a 1.8 GHz Core Duo, not a Core 2 Duo. A Core Duo is roughly 30% slower than a Core 2 Duo at the same clock speed. The 2.3 GHz AMD you've selected should do quite nicely; as far as I can tell, Athlon X2 and Core Duo are nearly identical clock-for-clock.

No, it won't be. An Athlon X2 6000 is a hot and power-hungry chip, and will all by itself pump out more heat than most of the entire systems on this site.
