I bought this case as the smallest full-ATX case I could find with 5.25" bays. Everything else is either gaming (no bays) or 80% fresh air. It is a budget case with a couple of surprises (like twisting off the metal covers to PCI slots irreversibly) and it's hard to do neat wiring but that is an acceptable consequence of being small. I installed a BeQuiet PWM fan and have sound deadening on order but both those extras are overkill. Overall I am more than pleased with what I got for what I paid but this is not a premium case.

Good for the price; simple but effective. Main gripe is that, for a new build, I needed to remove the front panel, and it's neither easy nor intuitive. After hunting around on Youtube, I found that there's a series of internal clips down each side, which need unclipping. Managed it in the end, but felt like I was going to snap or fracture the plastic in the process.

Good price, loads of space for hard drives.Materials are cheap but mostly metal not plastic.Not much room for cable management but all around pretty good. Hard to find a case with this much internal drive space now days.

The case is slightly large but has plenty of space for the motherboard and other parts. The sides come off easily and there are two thumb screws each side to hold them in place. There are plenty of bays for drives plus there are 4 screw holes in the base to mount a Solid State Drive. This is a key point as most SSDs are 2.5 inches. That is the right size fir the base screw holes. The wiring inside the case is high quality and it comes with black screws for mounting components such as drives
Purchased a number of components at the same time to build a new PC. The others were all of the highest quality. This was cheap and flimsy and the removable side does not even fit back properly. The side was so difficult to remove in the first place that I even phoned support to see if they knew of anything additional holding it in place. There is no indentation in the panel to grip it with and this compounds the problem. In the end I re-used my old case which, although it has no front USB 3.0 port, is vastly superior in every other way. I really should have returned it for a refund.
II have bought a fair few computer cases over the years but this is certainly the best I have had so far.I am NOT a gamer and I only build for general use (MS Office browsing, video editing etc) but that does not mean I want any old case, it has to look good and be east to work on and this case certainly is that and to top it all off it is at the bottom end of cost but bat the top end for value and features.To be honest I had almost given up looking for a case, as first and foremost I required 3 x 5.25" and 1 x ,3.5" bay on the front - I only found 2 models like that everywhere I looked and this is one of them... another bonus was that is is about 2" smaller than other cases of this type I have but is was so easy to put the ATX board in and to top it all of it is ...

Cheap case that is poorly made, none of the mounting surfaces or sides seem to be perfectly right angles to each other. Only out by a tiny amount, not enough to stop you installing components, but enough to be annoying and luckily the material used is thin, so there is a bit of flex in it to aid with the mounting.The front panel does not match perfectly with the side panels, the back panel cutouts for the PSU and I/O shield are not square (see photo)BUTI needed to replace a system fast. It was in stock, has a higher number of drive bays that its equivalents and was cheap. It will do an an interim case until more premium cases come back into stock
Clean lines and plenty of extra screws included. The front sections allow for 3 x full size inserts, such as optical drive, extra USB ports, etc.
It's cheap and it works, but it has a few drawbacks:1. It's very hard to do good cable management in this case.2. 2.5 inch drives have no way of being installed into this case. You will need to get an adapter (increasing the overall cost associated with this case, defeating its purpose), or let your SSD dangle.3. Due to its size, it is difficult to plug in the PCIE power connector into the graphics card. This difficulty is made worse if you have a hard drive in roughly the same area as the graphics card.4. PSU is top-mounted, which I don't like but that's a personal preference.The case is functional but not enthusiast level. If you don't mind how your computer looks, or if you don't care about cable management, this case will serve you well.
Some confusion with this being either 1*USB2 and 1*USB3 on front panel or 2*USB3, also front panel socket layout differed from images. Finally, the rear water cooling grommets are missing scuppering my AIO cooling option :-(Good little case otherwise, but a little light around the rear PCI slot covers.
