I am selling my iMac 27"which was purchased late 2013 in Bangkok.
Specs are:
i5 intel processor,
1TB HDD,
16GB RAM.
Fresh install of OSX Mountain Lion but can be upgraded to Maverick or Yosemite.
Only issue is the hinge needs tightening but can be fixed at an Apple service centre for free. No scratches or dents etc. Comes with original box, power cable, wired Apple keyboard, Apple magic mouse and a fresh install of OSX.

Can deliver to central Bangkok on weekends or late evenings in the week.
