Consider this TS140 thinkserver for $260 - comes with ECC ram: http://www.amazon.com/Lenovo-ThinkServer-TS140-70A4000HUX-Computer/dp/B00F6EK9J2/ref=sr_1_1?ie=UTF8&qid=1392441648&sr=8-1&keywords=ts140

While that poweredge would give you about 40% more power than the i3 thinkserver it will also consume almost 3x more electricity by the CPU (55w vs 160w) and create more noise. Plus the TS140 comes with a 1 year warranty.
