Very attractive case but only 1 ventirad so the PC heats up a lot. It's a shame
Good value for money

Good quality product! Quite spacious for a mini-tower and very well laid out. Very fast delivery.
Clearly not a top-of-the-range box, or even a mid-range one, but for the price, it does the job.
There's nothing wrong with Ryzen 3600 and 6750xt for this case.
Well, it's been 2 years of relatively regular tinkering and this tower hasn't yet cut my finger (I've lost count of the number of cuts I've suffered on 'scrap' office towers). So it does the job 5 stars.
Shipped quickly and matches the description perfectly. The price is unbeatable. The website is great and the information is detailed.
