I am sure your suggestions will work well. My experience is that most servers need LOTS of I/O capacity and not much CPU. CPU may be more of a concern with a MySQL/PHP server up to a point.
*) You may not want to use RAID 5, use RAID 10 for speed and buy more drives.
*) Use multiple PCI buses, i. e. ServerWorks HE(not LE) chipset boards like the more expensive supermicro ones.
*) 64 bit/66 MHz Gigabit NIC on PCI bus 3, more pricey one with 512k buffer
*) 64 bit/66 MHz RAID controller on PCI bus 2
*) 32 bit/33 MHz PCI junk bus 1
*) isolate video to the AGP bus or your junk bus
*) do NOT buy Compaq/Dell/HP unless they show your it is a SWHE chipset
*) Use a managed gigabit switch and watch it(heavy I/O should show most frames are 1. 5k)
*) Have several spare hard drives on hand especially for the 15,000 RPM drives
I am NOT an Intel fan, but for server I/O you need each PCI slot to work like a buffered switch, not like a shared hub. The server works chipsets do that, Intel chipsets do not. VIA chipsets are the worst for PCI I/O but are very good for local memory I/O for workstation applications. Actually I hate Intel and would like to have an AMD MP system at home... We use a LOT of NT at work and the network I/O is terrible compared to UNIX.
