Server Hardware Recommendations

[Michael Moss]

Hello All,
I have perused the archives extensively, but am still looking for a 
good answer to this: Does anybody have any server hardware 
recommendations considering the following?

1. Would like to run BSD 4.9 Release
2. Minimal Tweaking (do not want to tweak drivers etc)
3. RAID 2 or 5,  sought in this order (greatest to least)  SATA, SCSI, 
IDE
4. Dual processor a plus but not necessary

Im mostly concerned with Motherboard recommendations, preferably with 
built in ethernet and raid which works "out of the box".

What are some setups people out there have?

This is for a PHP/MySQL intensive website.

Thank you for your help.
