I'm considering replacing my Early 2006 20" iMac (2.0 GHz, 256MB VRAM, 500GB hard drive, 2GB DDR2 SDRAM) with a Mac mini Server, which I'd wipe the drives on and reinstall Snow Leopard client with both drives in a RAID 0 (needless to say, I'd hit the ground running with a Time Machine drive). Apple's online store's "Refurbished Mac" section frequently has both the Late 2009 model and the current (Mid 2010) model, the former (at $749 being $100 cheaper than the latter (at $849). So, my questions are: 1. Save for speed and other improvements on the newer one, is there any reason I should go for one generation of mini Server over the other? 2. I'm assuming that the earlier Server model simply requires a retail disc of 10.6.3 client in order to have it running Snow Leopard client just fine (i.e. with no driver problems), but that in order to do that with the Mid 2010 model, I'll have to find a copy of the restore discs for the non-server Mac mini. Is this correct? 3. In the event that I get the earlier model, will having a RAID 0 on the drive give me better, worse, or roughly the same performance as that of a 7200 RPM drive? I combed the forums looking for info on this and found nothing conclusive. That said, if I missed something, please feel free to point me in the right direction. Thanks for your time.
