I've found a Asus vento A8 for 50€ including a monitor and a keyboard. I mainly want it for watching movies and series on my living room. Also, the seller told me that it turns off randomly. I have a spare power supply and also a motherboard with a CPU in case I need to change it but i don't really know what the problem is. I could probably sell the monitor and keyboard for 15-20€. Should I buy it?
