Under which basis? If you want to get the best prize/performance ratio, this is the best choice, full stop!. You got to study in deep all
 possibilities, but regardless...
Sure. The basis for my suggestion is my(!) best trade-off between the amount of non-scientific work that I have to invest and what I finally get out of it scientifically. If you run into problems with your garage-built hardware (which can without any doubt be as good as any other hardware) you might be stuck with it and you might have to fix the stuff yourself. A major brand vendor producing server hardware can just not afford building sh*t because otherwise they are out of business within weeks because the 24 h exchange support eats all there profits. Since I could not afford being without my compute server for more than a couple of days, we decided to go for a brand-name hardware. All major rack-server vendors, including ours, come and exchange your hardware within 24h in case of a defect. I just had this case a couple of days ago (processor heat death due to a damage fan) and I was really happy to see my server running again after 24 h without having to do more than a phone call.
 Just checked and best you can get for a reasonable prize there seems dual
 PIII. That was OK maybe last year, but now for not a much higher price,
 but no big brand (the ones I know, Siemens, compaq, dell, and IBM, do not
 sell AMD's and dual P4 are still too expensive). You can get dual ADM
 athlon 2000 which definitively runs faster for mainly the same prize but
 you have to renounce to the big brand name.
We are running Siemens hardware and we are very satisfied, but I think there are tons of comparable systems from other major producers.
 I am pretty sure, I am also pretty sure that they are not the best
 alternative nowadays, :-)
There are always systems with newer, faster, etc., hardware. The systems I'm talking about are designed for stability, which might cause the vendors to stay with a particular hardware combination for a few month longer. We have had half a year of uptime with some of these and the reboot that interupted this was more like a vodoo idea ("hm, it might be good to reboot from time to time, no one knows...").
