[X4U] entry level iMac supports 16GB?

[Joe Sporleder]

Is it a fair assumption that all current iMacs have 4 memory slots and will easily support 16GB of RAM? Apple's online refurbished store has the current entry level iMac at a refurbished price of $999. I have a use for it and don't need a ton of storage or high end graphics, or even a super fast processor (2.5Ghz quad-core is plenty), but being able to put at least 16BG of RAM in it would be great. Apple only lists this model as supporting up to 8GB of RAM, which in their case could that be more of a marketing issue rather than a technical issue?
