Okay... so I started my build today. Apart from the nasty surprise that I was minus one of the CPUs (stuck in customs) everything went smooth. I'll add the extra CPU as soon as it gets here.
So my initial plan was a PC-323 case which then became a 4U i7-4771 build:
Case: X-CASE RM 424 PRO
CPU: Intel Core i7 4771
Motherboard: Supermicro MBD-X10SAT-O
Controllers: 3 x AOC-SAS2LP-MV8
PSU: Seasonic X-1250 1250W PSU
NIC: Intel X520-T2 Dual 10-Gigabit Server Adapter
OS Drive: Samsung 840 Pro 512GB
Cache Drive: OCZ IBIS HDSL SSD 240GB
Storage Drives: 11 x 4TB Seagate Hybrid, 3 x 3TB WD Green, 4 x 2TB Assorted, 4 x 500GB Hitachi
I quickly realised with the amount of transcoding going on with Plex I needed more horsepower. I also need the case to be smaller.
So here's what I'm in the middle of building:
Case: X-CASE RM 424-S (550mm version of the 424)
CPU: Dual Intel Xeon E5-2695 v2 (12-core, 2.4Ghz for a total of 24 cores)
RAM: 128GB ECC Registered DDR3
Motherboard: Supermicro MBD-X9DRH-7F
Controllers: 3 x AOC-SAS2LP-MV8 & onboard LSI i-SAS RAID
PSU: Seasonic X-1250 1250W PSU
NIC: Dual Onboard Gigabit
OS Drive: 8GB Corsair Voyager Flash
Cache Drive: Samsung 840 Pro 256GB
Metadata Drive: Samsung 840 Pro 512GB
Plex Cache Drive: Samsung 840 Pro 512GB
Storage Drives: 12 x 4TB Seagate Hybrid, 3 x 3TB WD Green, 4 x 2TB Assorted, 4 x 500GB Hitachi
