Best Configuration for New Imac?

[ioannis2005gr]

Get a mini, preferably the 2.3 quad, and a bigger screen, like a 24 inch 1920x1200 ips one. The 21 is cramped IMO.
You can get the base model and fix the RAM and SSD for a low price yourself.
Mini 2.3 quad 799
Dell U2412M 309 (IPS 1920x1200)
16GB RAM 120
256Gb SSD Samsung 840 EVO 179
Cable for extra drive 30
Total 1430$
To have a little better performing iMac (CPU wise), you pay $2099
All other options are outperformed by the solution I showed here, yet you will never have 1.25Gb with 250GB of SSD and not have a nice large screen with better warranty and better ergonomics, and a much lower total cost of ownership as the Mini's go down less in value.
You can even slide the Mini in your pocket and work somewhere else with it.

I agree... but I'll wait (until late Oct.2013) for the newest and latest Mac Mini before I decide (I prefer 24'' ASUS PA series monitor).

I noticed that 21.5 BTO iMac (Haswell i7 /1TB Fusion Drive / 16GB RAM) is a wonderful choice!
