I’m buying a pc and I was wondering if this used one is okay: Motherboard: ASUS P7H55-M
Processor: Intel Xeon X3470 2,93GHz - turbo 3,60GHz
Graphics card: Radeon RX480 8GB 
Ram: 8GB (2x4) DDR3
HDD: 1TB
SSD: 120GB
Cooling: Cooler master hyper TX3
Power supply: Silver power 400 400W
Windows 10 Home

And this guy is selling it for 350€. Should I go for it?
