Will update this thread as the project progresses. Currently I have : An old Gateway E-series with a P3-733mhz, 128mb RAM, and a handful of empty drive bays. Drives I have now : 1-200GB PATA 1-250GB PATA 1-120GB PATA on order : 4-250GB SATA I also have a 4-channel SATA RAID controller. I haven't decided what RAID config I will be using yet, I'm thinking probably RAID 5 for the 4 SATA drives (effective 750GB array), and the PATA drives will just be network attached, not in an array. The SATA drives should be here next week and I will take some pics of the install. I will be using FreeNAS (www.freenas.org) as the operating system - it's a FreeBSD (Unix) based system - I don't have much experience with it, but I have friends who do, and they've said it's easy as pie. The OS can be installed to a USB flash drive or CF card - you don't even need a boot drive.
