Fair price for this beast?

- late 2009 27-inch iMac
- 3.06 GHz C2D
- 1 TB HDD
- 12 GB RAM (2 x 4GB + 2 x 2GB)
- wired aluminum keyboard (extended, English); no mouse
- OS 10.6.8
- original disks and packaging
- case and monitor in excellent condition - no dead pixels.

Anybody?

I'm finally going to sell this one maxed out @ 16 GB, with the wireless Magic mouse.

Any ideas? Mac2Sell.net pegs it at $1280, but I have no idea how reliable that site is.

TIA

$1280 sounds about right for a C2D. If it was an i5 or i7, I'd expect at least $1400. The RAM adds almost no value at all, as a new 8GB kit is only about $40 or so.

Thanks.
