recomendations please for new freebsd development system

[vizion]

Hi

Like the title..

I need to build a new systemsupporting a substantial mysql database
application for a development team and also able to provide:

1. fast as possible compile times
2. raid  6 support with 6-10 terabytes of data storage
3. 1 terabyte fast data storage
4. 8G or more of ram
5. excellent graphics performance and capabilities with high quality
sound/video  supporting dual high resolution monitors and surround sound.
6. Back up facilities for 6-10 terabytes.

Would anyone be so bold as to make some recommendations for a reliable
motherboard/processor combination on the assumption that this is to be a
dual processor system running freebsd 6.0

Thanks in  advance
