Long story short, built this high performance freenas server at the end of the summer after collecting most of the parts over the spring and summer.
The final bits were the microcenter cpu/board combo deal as well as the last 2 toshiba drives... yes I know Toshiba drives... At least they were refurbs, and they are in a raidz2 volume, just in case.
The quad core helps overcome the limits of the on-board realtek network adapter, achieving just over 60MB/s write performance on an unmanaged gig hub while replicating data from my older 6x1Tb NAS, was very pleased to see those numbers.
The MSI board, while not a powerhouse, does have some decent heatsinks on the VRMs (a nice feature over the lesser boards you see in most dual-core cpu/mobo combos)
The xclio case was a steal at the sale price, not sure I would have even got it at the full $60+ price but it has a really cool fan control with touch buttons in the front, you can turn the fans on/off, LEDs on/off and fan high/low speed settings. Came in handy when I was burning in the system (when I took the photos), I had it on high speed and it helped keep the temps down since all the HDDs were running "badblocks -svw" simultaneously off a bootable SLAX usb.
If all works well, this will assimilate my previous two freenas builds - one is already gone, my original celly/p43 w/ 2Gb ddr2 and 6x400G raidz2 is already dissembled and my current 6x1Tb will eventually be sent over to my parents house as my cloud mirror - if they ever ditch cable 'net and get FIOS for the BW caps...
