Looks like a few hundred dollars (USD) less if you build yourself. I'm not sure what's available to you but this is as close as I could get. Case is up to you but I went ahead and added the NZXT S340. If you want to price match, you could get a better CPU and an SSD. I'll build that one below as well.
Here's the most comparable build.

Here's the price matched build.
For the same cost, you can get a much better CPU, motherboard, psu and faster RAM and a 500GB SSD. This would blow that Predator away.
Thanks for your help.
could you do one more build for me please?
Do you think this is worth the money or could i build somthing much better for the same price or less?
ps im in the UK
Well, it still looks to be a couple hundred less if you do it yourself. USD. You still get a 500GB SSD and faster RAM. If you were to take out the SSD and match the RAM, you'd easily be about $500 less than the prebuilt. I will always recommend building your own over pre-built.
