Do you have you a question about the Horizon Thunder Ryzen 5 5600 RTX 4070 Gaming PC?

4.9 / 5 20 reviews


last week

Jacob from customer services was very patient and helped to amend my order without hassle. Product came at expected time to the highest standard. PC works perfectly as expected.

Excellent PC, does exactly what you would want it to do. The only reason I don't give it 5 stars for value is because of Nvidia's graphics card prices, though I cannot blame that part on CCL Computers. They provided excellent customer service as well and even though I opted to change out the motherboard, which led to requiring a different case as well, they still got it out and it arrived when it said the initial order would. Overall very happy with this product so far.

Speedily put together and exactly as ordered. Can even turn off LED gubbins easily which is awesome. Great customer service.

Absolutely awesome value for money ,loving the power and speed and playing starfield looks absolutely beautiful

I'm really enjoying this PC. I wanted to change a component after I put through the order before it was built, the CCL team were great and personable, making this change really easy. I was eqaully pleased with the price and delivery time, I'm sure I will use them again.


4 weeks ago

Very good and worth the money. On occasion the CPU does overheat. But thats the only issue Ive had so far. Really loving it!!


4 weeks ago

This PC is outstanding, I customised the stock set up with a bigger processor and GPU to run easily at 1440p consistently, which it does without any effort. It stays beautifully cool and is quiet. I am delighted with this set up as it meets all of my needs on a budget. Thank you CCL for delivering on all of my requirements, this is gaming heaven! I would absolutely recommend to all.


last month

great product could not ask for more

Super fast and reliable and arrived sooner that expected, really impressed with how quick it was built and all parts work perfectly and people are even envious of my build! Top company.

Enjoying this Gaming PC immensely, No more sticky, sluggish AAA games

The Horizon Thunder PC is an incredibly capable peice of kit and for the price! Absolutely no complaints here. In todays market and at this price range this PC should not be able to do the things it does!


2 months ago

This is the second PC I've bought from CCL (the first was an entry level PC for my parents) and it's a banger! Technically the cable management is next level and some of the best I've seen, full stop. Value wise I can't seem to find a better deal or anything even close! Runs brilliantly and future proofed for many years. A great entry level gaming PC for my son and I'd argue could easily compete with some of the more 'hardcore' gaming PC's being offered by competitors at much higher prices! Very happy customer.

Perhaps should of upgraded the stock cooler on my prebuild but didn't think about it enuff. Overall amazing

This is my first gaming desktop, and it is brilliant. I'm obviously new to PC gaming, but the CCL website and customization options were super clear and easy to use, and made the process very user friendly. The PC looks great, works great, was easy to set up, and runs smoothly and quietly. The customer service was also brilliant throughout the process - there was apparently an issue with the case I originally selected (stock shortage I think from the manufacturer), but not only were the team able to suggest alternatives, it still arrived a week earlier than originally suggested. Very happy with my purchase!

Everything just as I'd ordered, well packaged and safely delivered. Very happy with my purchase.

Absolutely brilliant service from CCL. * Fantastic price for spec of PC compared to other websites. (Ryzen 7 5800X3D & GeForce RTX4070) * They phoned with advice on alternative mobo - to make the most of my build without spending much extra. * PC delivered much quicker than expected - within one week of order being placed. * Excellent communication and advice throughout. CCL will be my first choice going forward - even better than PC-Specialist, who I've used a lot in the past.
