Comments on server hardware configuration please
We are building a dedicated server for about 300 sites which are mixed type - dynamic/static.I need your opinion on the configuration below. And if any of you have any experience with some piece of hardware below, please let me know.
Tyan Tiger MPX S2466N mobo (dual Athlon MP, up to 4GB PC2100 DDR RAM)
Dual Athlon MP 1600
2 GB PC2100 registered DDR RAM (4x512)
2x SCSI IBM Discovery 18GB 10K HDD

+ good cooling of course

Is this hardware good? What about performance? Would it hold 500 average accounts?
