  1. Zippu

    really good for its price can run the games i enjoy and love with ease

  2. John difalo

    i bought this product out of curiosity. Its really good at running my sons favourite game, Apex Legends

  3. Sean Oreilly

    Good solid pc but if you ever want to upgrade graphics bare in mind it only has 350w of power so limited to graphics card you can get

  4. Jayden Roberts

    Ok so I haven’t bought this pc yet but I’m buying it in a few months and I noticed that a different company are charging more for pretty much the same components I can’t write it there so I’m writing it here it’s just so bizarre how there selling the same product with a higher price the only difference between them is the watt this has 350 the other has 450 but when you go on amazon it’s literally 40£ like how Is this allowed I’m just warning people.

    I Purchased the same PC last year and it came with a cheap computer case that could fit up to 2 120mm fans (RED LED) in the front. My friend, who paid almost £100 less has a tempered glass side panel that can fit up to 4 120mm fans (RGB) in the front with the same specs. I like Storm Force but they need to get themselves together a little. My friend got better than me and he paid almost £100 less. Overall MY experience is very good with Stromforce and would recommend 100% (if they got things right).

      First of all we would like to thank you for taking the time out to leave a review on our product.
      we would like to take all reviews on board and aim to improve the overall customer experience where we can.

      in regards to the change in chassis, we understand your frustrations. However, some components including chassis do become no longer accessible and we have to change them out and especially during the current global climate, this is not always foreseeable.

      Thank you again for your words and recommendations.

    I am fairly disappointed in this PC, I bought it from argos and on the description of this PC, it said it’s a good PC to get into entry level gaming. However, whenever i try playing Fortnite (which is listed as an entry level game), my frames stay at around 40 and i have most of my graphic settings on the lowest that they can possibly be. I am not happy with this as a £200 Xbox One S is capable of running fortnite at a steady 60FPS whilst having decent graphics. I have tried everything to increase the frame rates but nothing has helped. Overall i am really disappointed and feel like i have wasted my money as the PC is not how it is described.
