hey this is my first post so here goes, I'm just building a small home server to backup my media and office documents. I want a "Semi-foolproof" solution. I have chosen to buy a Powermac G5 WITH DUAL 2.5GHZ PROCESSORS and 16GB OF RAM (i got it cheap on ebay) and i think i'll whack in a seagate barracuda 1tb drive for the OS drive to top it off. As for my bulk storage i need atleast 4terabytes Minimum (preferably upwards of 6). So far I'm thinking an external raid enclosure (like this ) with 4 x 2tb Seagate Barracuda green drives in RAID 5 (which is supported by the enclosure mentioned previously) The final vision for this setup is a neat home media server, backup location and home network gateway for remote login etc. I would also like to use the G5 for some Logic work and other "mac only" programs. This will be in edition to by main P.c. as well as my wife's business laptop (macbook pro) and my business laptop (toshiba). I intend to run Lion Server on the finished rig. My simple question is: Will It work? Any feedback, suggestions or criticisms welcome. Some other things that are bugging me are Will raid 5 be enough protection for my data? Will my external raid array be as seamlessly accessible as an internal one? Will the G5 be able to handle all this? Will this server be windows compatible? Do I have to make any special considerations when selecting an external raid enclosure (i.e. is the enclsoure i listed above mac compatible)? Thankyou for any help!
