If it's going to be write intensive then the RAID controller will be the most important thing. A dual p3/500 with a write-back cache will smoke either of the boxes you mention using software RAID on write performance.

As for the compute intensive side (complex joins & sorts etc), the Dell will most likely beat the Sun by some distance, although what the Sun lacks in CPU power it may make up a bit in memory bandwidth/latency.
