considering installing FreeBSD on a Dell 2800 and need a wee bit of advice

[Pancho Cole]

Greetings, I currently am using Solaris (SPARC) boxes in my small business, 
but I am considering migrating to FreeBSD when I build my next mail server. 
I am considering purchasing a Dell 2800 multi-processor with RAID 1 and 
RAID 5 on the disks. Whom might I contact to find out if this would work? I 
have had no experience with FreeBSD but I started off using BSDI years ago, 
so the BSD model is not a complete stranger to me.
