I have an iMac 27" (Late 2009) to get rid of.

Specifications (will fully confirm these once I have reinstalled MacOS):
CPU: Core i7 (Lynnfield/Nehalem), Quad Core 2.8GHz
Memory: 16gb DDR3
Graphics: ATI Radeon HD 4850 512mb (Still fine for HD Video and some light gaming)
Storage: 250gb Samsung Evo
27" 2560x1440 Display
Also has Bluetooth and 802.11n (2.4GHz and 5GHz WiFi) along with Gigabit Ethernet
Running MacOS High Sierra (this model doesn't run Mojave nativally)

Just note - in the past there has been some soldering rework work done on the motherboard by myself to repair it for the graphics card to screen connector. It has been running upwards of 5 years since I done this but thought I'd mention it. There is also some faint(!) lines that appear on the screen however I honestly don't notice these with use.

Would run later versions of Linux very well otherwise I believe High Sierra is supported until roughly September 2020. Can potentially run Windows 10 also.

As I want this gone I am asking $200 for the iMac (as is!). I will not ship however can potentially drop off in Wellington. It'll be provided with an Apple Keyboard + a Trackpad and have a fresh install of High Sierra installed. I do also have a Magic Keyboard which charges over Lightning which is yours for $50 more.
