Not helpful to you, but the parts for that are like £400-450.
I don't like that computer at all. Plus, Amazon is essentially Wish now. I wouldn't trust any parts that came from there, no way would I ever buy a PC.
I bought my girlfriend a pre-made computer and the price was almost 1:1 if I were to buy the parts myself.Came to £1050 and her PC was £1100. They make profit from buying in bulk, getting discounts, they are a business and of course need to make a profit.
But if the parts totalled up comes no where near if you were to 'build it yourself' then I'd run a mile. Building a PC yourself is barely even worth it nowadays, but in the case of that PC, 100% go yourself. I recommend looking at some proper PC websites.
Happy to be corrected.
