Is this PC good? Should I go for it?

Overall the price per performance ratio is decent. But the Hard drive is no name, and there's no SSD. For £1,089.99 you would be able to build a stronger PC with an OS and a SSD. Plus a name brand HDD.
In addition, the warranty probably covers the computer as a whole, and not the individual components. If you build it yourself, you get 1,2,3, and up to 5 year warranties on the individual parts.
