Antec Earthwatts 500 Noise?

I recently finished a computer that includes the Antec "Sonata Designer," basically a white Solo with an Earthwatts 500 power supply included. The computer itself is nearly silent. The power supply is another matter: it emits a low-frequency hum, a higher buzz, and seemingly a cyclical vibration tha...

Compupro, in 1980. S100 bus, dual 8085/8088, with an 8087 math co-processor, 256K of static RAM, dual 8" floppies, nine serial ports, three terminals (Heath H-29) and a dot-matrix printer. It ran MP/M (a multiuser version of CP/M), and allowed simultaneous execution of 8 and 16 bit programs. Utterly...

Just be aware that there may be some differences between the consumer and the quadro versions. I put a Zalman 900 on my FX2000, and I had to drill a hole into one heat sink (on the reverse side of the board) for the attachment to work properly. It was easy enough to do. And yes, it does make a HUGE ...

If there is no hole for a case fan, it is probably better to leave well enough alone.

Appropriate memory shows up pretty regularly. Here I pay about $20 for 256MB; local conditions may of course vary.

Have anyone exchange the CPU fan? It's seems that DELL is using a special 3-pin connector for the fan, but is is just to solder together a the cables from the old CPU fan to the new CPU fan?

RAID for anything other than redundancy on a 500MHz machine is way overkill. You exceed the capabilities of the DMA channel at about 40MB/s, give or take. Any modern drive can do that by itself. The server for my small company is a dual PIII (550MHz) and it is more than plenty. It runs the usual Apa...

You don't really need 74GB for your application. 36GB, or even 18GB, would be plenty, as long as you have a large IDE drive to hold you bulk data (say, 300 or 400GB). You need the bulk drive only if you work with media files, like music or videos. Without those, disk capacity just does not fill up t...

I frequently run two virtual machines (XP, W2k) simultaneously on a FreeBSD host. I give the VMs 750MB each; 3GB works fine for the total machine with room to spare.

One simple question: have you used SCSI drives? If so, which ones? I know the benchmarks well, but they do not correspond with my experience (or perhaps my workloads). The Raptor is of course a fine drive, and a very large step up from a 7.2K RPM drive. It should be considered if a quick, small capa...

The controller is more likely to be PCI-X, though you can get any flavor you want.

The only other way really to speed things up would be to use RAID. That doesn't help latency much, but it does improve serial transfer rates if that is important to your applications.

The differences between 7200 RPM drives is really pretty minor. If you want to speed things up you really have to go to 10K RPM (Raptor or SCSI) or a 15K SCSI. You can get these to be quiet with some work, but they are not silent. FWIW, my main workstation has four SCSI drives: 3 15K and 1 10K. The ...

Agreed. For a server, you really don't need ANY horsepower. The standard on-board chip for servers has traditionally been the ATI Rage 128. It is silent, consumes little electrical power, has little computing power, and is perfectly adequate. You can choose a comparable nVidia or Matrox flavor if yo...
