The Dell box has
1. Chassis with space for 6 disks
2. Xeon 2.4 GHz CPU
3. 32GB RAM
4. 4x 500 GB disks in RAID 6
5. price $5563

While I like RAM as much as the next person, very few DB servers really 
need 32GB of RAM.
Especially since the DB size is 35 GB.

RAID 6 is cool technology, but does not make sense with just 4 disks.  
There would be 2 data
disks and 2 checksum disks.  Every logical disk block write, would do 3x 
disk reads and 3x disk writes.

You might consider something like this.

It has

1. Chassis with space for 6 disks
2. Dual quad core AMD 2.0 GHz CPU (probably overkill, FYI I am CPU brand 
agnostic)
3. 8GB RAM (room for 32GB)
4. 3x 500 GB disks, I suggest mirroring 2 disks with the 3rd for a hot spare
5. price $2300

To spec out a system right, we really need more hard numbers from your 
current box.
Like DB data cache hit ratio for its RAM size and disk % busy time.  
Perfmon is a great tool.

Hope this helps,
