Review: Great case, tricky planning and build - The main gimmick of this case is the ability to mount psu at different heights depending on your needs, if you want watercooling you'll need to place it lower for more room at top, want a long gpu place it higher to increase clearance upto over 400mm, want both you'll need a sfx psu which is easier to cable manage anyway, want a thick gpu, upto 4 slots but anything thicker than 2 you won't be able to have bottom fans or drives Pros. Compatible with fullsize components Looks nice(imo) Easy front panel connector Relatively compact Outstanding build quality Affordable Cons. Horrible cable management options Screws come mixed in bag Limited compatibility(may not match the maximum listed dimensions) Parts used in my build GPU: 7900gre hellhound PSU: Toughpower gf3 1000w CPU: ryzen 7 7800x3d Motherboard: mag b650m mortar wifi Cpu cooler: deepcool assasin IV(may be unavailable due to recent ban, I bought it a while before I learned of the Russia issue) Fans: artic 120mm 5 pack, I could only fit 3 with my gpu blocking the bottom 2 Would definetly reccomend to experienced builders or anyone willing to do the research on each components compatibility(or want to take the gamble) Edit: it's also important to mention that come cpu coolers like mine will prevent you from installing the side fan bar, whcih means even tho there is room between my cpu cooler and psu for a fan I can't put one there since the part the fan attaches to is blocked, because of that I could only fit 3 fans, 2 on the top and 1 in back, all exhaust unfortunately whcih means it's a negative pressure system, air can get in through the sides but this will lead to some dust build up
Review: Very cool case - Awesome case, I was able to fit a full water cooler, fans, and a 3 fan 3060 into it. Very easy to assemble and compatible with many different options. Some of it is plastic, some is metal so do with that what you will. Very hard to cable manage it but I got it to fit onto my desk better anyway so it doesn’t bother me.

### ⭐⭐⭐⭐⭐ It can fit A LOT. Amazing discrete build!!
*by D***6 on April 6, 2026*

Easier to build on than ANY full atx case. And it comes witg brackets for EVERYHING. It could use a simpler bracket for the psu especially. Especially to take advantage of an sfx, but everything else is as spedicied. Its a pleasure to build on.
