High Performance i7 Gaming PC (Play Watchdogs,Dota 2 in High) in Serangoon Central, Northeast Singapore for sale

Selling my used gaming pc. Both the cpu and gpu are extremely powerful and can play most of the latest games in high settings. The case is very big and can support future upgrades and the psu also allows for upgrades or additional components. Everything is in great working condition but the only thing is that the case top window has marks that cannot be removed. Other than that the case is in good condition. Will provide 3 days personal warranty and self collect at Serangoon Central as the item is pretty big. Selling at $700 and will throw in a TP Link wireless pci adapter if bnp is offered. Thanks and you can contact me at 93369965 for any questions.
