my take is iMac 2011 or newer from the usa refurb store is a good deal.

this machine is an example .
first off it will run up to 32gb ram
second it can use snow leopard or lion
third it has a good cpu it is a little weak on the graphics card.
********************************************************
so this next model has it all:
http://store.apple.com/us/product/FC814LL/A
it can use 32gb ram
it can use snow or lion
it has a good cpu
it has a good graphics card
it has t-bolt
***********************************************************
right now the promise pegasus is costly. due to floods in asia

I grabbed one earlier in the year a 6 drive model for 1320 usd
this unit allows 6 drives setup in any which way but loose.
the trapped hdd in iMac is a thing of the past.
I use three drives as a time machine.
I use one as an osx (intel ssd)
I use one as a super duper clone of the intel
I use the internal as a windows osx.
so i have a double boot machine with backup.
now i am doing this with a mac mini server as I sold my 2009 iMac.
I can't run snow and I am thinking of getting the 2011 older imac.
