Congrats! You just paid for shipping and got the server free.
If anyone will try to tell you it's garbage - don't listen. It's still the cheapest way to get multicore performance with up to 768GB RAM. Downside? It's noisy and power hungry. If you can live with that - you will enjoy it. It's well designed machine that will serve you well.
Well you can't put two I7s on one board :)
That's why I'm saying - it's a cheap way to get to those levels of performance, not the best way.
In 90% of cases small 920x would be sufficient for homelab, but if someone likes big, loud enterprise machines - this one is oldie but goodie.
