I'm afraid that won't help. That was like 6 years ago and all the hardware isn't available any more. It's a Xeon 4 core, an affordable workstation/server mainboard that happens to be very efficient in idle, 48GB of RAM and a bunch of harddisks. I started out with 6TB and then bought the best size/price hdds, which should currently be somewhere in the 12-14TB range if I'm not mistaken?

I got the idea from the German computer magazine c't. They occasionally test mainboards and do recommendations for self-built home NAS, office or gaming rigs.
