Have made some changes to my setup at home so have a bunch of things that are now surplus to requirements. Prices as listed below and I'll cover any shipping costs. Pickup is in Wellington, Wilton or CBD.
Sapphire Nitro+ RX580 8GB (In original box - Purchased April 2019 PBTech) $180 [SOLD]
Airport Express A1392 $60 [SOLD]
3x Echo Dot 3rd gen, 2x white and 1x black. $40 each [SOLD]
I'll probably add the SF600 PSU to this list but just need to check if I still have all the cables and stuff that came with it.
PM if interested.
