I'm planning to make a multi-purpose powerful home server running file shares, VMs and all that stuff. I'm just undecided whether to go for more powerful dismissed server stuff(Xeon E5-1650v2) or new less powerful hardware(E3-1231v3) for about the same amount of money. The problem is that I'm going to use a lot of PCI lanes and a lot of CPU power since this server will have to run Plex, streaming multiple 1080p streams at once, surveillance software with 5 3MP IP cameras constantly recording and encoding in H.264 format, OS X Server with Mail, Calendar, Contacts, and Time Machine Services, pascom MobyDick PBX, etc. As for PCIe devices I'm going to be running two basic gpus for the VMs, two dual-port gigabit NICs, an LSI HBA, and a TV tuner. The only thing I'm uncertain of is whether the dismissed server hardware is going to be worth it or if I'm better off buying new hardware. Has anyone had experiences with used server gear?
