Dell Dimension E521 Pentium D
are you sure the E521 is an intel chip? seems the E521 is and AMD and the E520 is the intel. THe AMD model is better then the intel but that won't matter much in this situation.
2 GB DDR2 800Mhz single channel
1 7,200 SATA 3GBs
The synology doesn't give any detailed specs but if its pushing a 1.67 dual core its not hard to guess that would be an atom processor, its running RAID 5 which will operate faster then a single SATA drive, it also has gigabit ethernet support which the dell doesn't, but that won't matter unless you are operating on a gigabit switch.
the synology sounds like its got great I/O hampered by poor processor/ram speed.
Easy choice.... DELL.
