This is an extremely fast windows 10 computer with really good specs. It works perfectly fine; nothing is wrong with it. Perfect for gaming and video editing. Extremely easy to upgrade. I am offering a 3 month guarantee so you can buy worry free. Os: Windows 10 CPU: i7 3770 GPU: msi rx 580 gaming x edition Ssd: 120gb Hdd: 1tb Ram: 16gb Motherboard: Asus sabertooth z77 This pc is a high end build with all custom pc parts. It has a very nice GPU which allows it to max out almost any game 1080p. The rx 580 in this pc will outperform the gtx 1060 in games such as fortnite and the i7 cpu allows it to keep smooth frame rates and do editing tasks no problem. The ssd allows the pc to boot lightning fast, and any game on the ssd will open super quickly. I built the pc in a brand new case with an edge to edge tempered glass side panel, and I installed a corsair water cooler to keep the cpu ice cold so it can run at faster speeds and last longer. I'm selling just the pc, and I can add a Wi-Fi adapter if needed. Price is negotiable, and feel free to ask me any questions.
