I am selling a brand-new, custom-built gaming PC or a very powerful desktop / workstation PC. You are getting someone to build and test the computer, for less than the cost of the components alone! I will provide a 1-year warranty. If anything happens to the hardware during that time, I will repair for FREE. With this system, you will get a Gigabyte Z390 AORUS Elite ATX motherboard, an Intel Core i5-9600k Six-Core CPU, 16GB of DDR4 RAM, a 250GB NVMe Solid-State-Drive (SSD), a Seasonic 520 Watt Bronze Rated power-supply, EVGA GTX 1660 Ti 6GB graphics card and Windows 10 Professional. This is all housed in the elegant Thermaltake Core G21 computer case. The system has gone thru extensive testing to insure component compatibility and stability. The following components are included with this computer: 1) Gigabyte Z390 AORUS Elite Intel Z390 LGA 1151 (300 Series) ATX Motherboard 2) Intel Core i5-9600k Coffee Lake 3.70GHz (4.60GHz Turbo) LGA 1151 (300 Series) Six-Core CPU 3) Cooler Master Hyper 212 LED CPU Cooler with Red LED PWM Fan 4) Corsair Vengeance LPX Black 16GB (2x8GB) PC4-19200 2400MHz DDR4 Desktop RAM 5a) Thermaltake Core G21 Tempered Glass ATX Mid-Tower Computer Case 5b) Two Enermax 120mm Case Fans 6) SeaSonic S12II-520 520 Watt Bronze PSU 7) Samsung 970 EVO 250GB NVMe M.2 2280 SSD [Win10 OS] 8) No Secondary HDD [extra storage] 9) No DVD-RW SATA Drive 10) Gigabit Ethernet Wired Networking 11) No Wireless AC / Bluetooth Networking 12) EVGA GeForce GTX 1660 Ti XC Ultra Gaming 6GB GDDR6 Video Card 13) Windows 10 Professional 64-bit OS Note that the component cost alone is over $1200 (w/ tax), and that doesn't even include assembly, test and the 1-year warranty that I provide! The computer only includes what is listed above. This means *no* monitor, keyboard or mouse. The computer is ready to go, but it can be customized to meet your needs. More/less RAM, larger/smaller SSD, add WiFi, different graphics card, etc. Just ask!
