I paid more for a 2.2 GHz 3500+ two months ago! > 2) Recommended case/power supply ? I went with an Antec Sonata, which out-of-the-box is hardly silent, but it's solid and pretty easy to work with. Then I added the foam kit for it that quietpc.com sells. I had the case for a while, and when I recently upgraded (from a PIII 866 to the AMD) I decided to get the foam kit. Took a bit of fiddling to get everything in, but the difference is very noticeable. It's now similar in noise to an idling laptop. This is with the stock AMD cpu fan. The case came with a quiet power supply. I'm happy. I chose my graphics card largely for lack of fan - I got a Gigabyte GV-NX66256DP2. Works well with either the kernel drivers or the nvidia drivers. Most of the remaining noise in my system seems to come out the rear, where the fans are. I put the case about 8" away from the back wall and put some foam acoustic treatment on that wall behind the case to reduce reflections off the wall. That made a noticeable difference. The one remaining irritant is hard drive noise. The Sonata 3.5" drive mounts are supposed to reduce hard drive vibration coupling to the case, but my main drive still makes quite a bit of noise wheen seeking. (I don't hear whining, but I do hear fast "clunky" noises.) I moved my "audio" drive up to the 5.25" drive bay, mounted on one of these ... http://www.newegg.com/product/product.asp?item=N82E16817991002 ... largely for cabling, because it was the only way I could get that drive on the second IDE channel; I was having problems with drive performance with lots of tracks in ardour. Seems better now. As a nice side benefit, that drive seems quieter now. I may get another of those 5.25" mounts and try putting the system drive up there too. > 3) The MSI box says it includes an nVidia nForce3 chipset, which I > assume means that there's an audio/video chipset on the mobo.

(Btw, I use the kernel nv driver, not > nVidia's binary driver). No idea, sorry. BTW, nforce3 doesn't automatically mean it has onboard video. My nforce 4 board doesn't. Onboard audio is likely. I just disabled mine in the BIOS. > 4) I assume I'll have to buy new RAM. What should I buy ? Something compatible ;-) I went with 1 GB of Kingston ValueRAM. The system reports it as 1004 MB, but hey, it was cheap :-p > 5) The CPU includes a fan, but should I get something more powerful ? I'd try it first. Mine seems fine. I was afraid it would be very noisy, but with all the padding in my case I don't hear it at all over the (quiet) case fan and PSU fan. > 6) How can I best reduce the noise from this system ? See above :) > 7) Am I correct to assume that this system runs in a 32-bit more as > well as the 64-bit ? How do I determine which mode I'll run in ? I'm a gentoo guy, so I just read their 64-bit guide and followed that. So I'd advise to read whatever info your distro provides about the matter. Once I was up and running, I just use the system as normal... I rarely if ever have to think about how many bits. The one inconvenience is that sometimes a gentoo ebuild that's marked stable for 32 isn't marked stable for 64 yet. -- Paul Winkler http://www.slinkp.com
