Delidded/Lapped i7 4790k @ 4.9ghz (I have not shipped the server to the datacenter yet, I might push to 5ghz, but I'm not sure it's worth the risk as 4.8 is stable after 8 hours of Intel's burn test)
GIGABYTE UD5H Black Edition
32GB of 1866mhz RAM (Kingston Hyper X Fury)
Samsung 850 Pro with RAPID
Two HGST 1tb drives with 32MB of cashe in RAID 0 for backups. (250MB/s) I'll also do true backups weekly.
