Box Contains COSMOS II 25th Anniversary Edition Computer Case Review: Amazing Case! Fits a LOT in! - This thing is a beast! Fantastic build quality, the kind I've come to expect from Cooler Master. The case comes packed in a well nicely printed box showing off the contents inside. Inside, it is protected by two very large pieces of moulded polystyrene and a plastic bag. The case comes with all the necessities including motherboard mounting pegs (& the obligatory screwdriver head), 5 case fans, and a magnetic blue LED bar and the head unit already wired to the installed fans. The case itself is heavy, around 9-10kg! CM made the right call by incorporating the very stylish carry bars (the legs also double as extra carry bars). The shaped glass is tempered and has a dark grey/black tint which thankfully reduces the very powerful glow from the LED bar down to a tolerable level in dark environments. The glass panels act as doors on both sides, releasing with a push of a latch on the back of the case. Both the rear and front sections of the panels are reinforced with metal plates to hold the weight of the glass. With the removable drive bays both in the main area and below (resting infront of the PSU), there is plenty of opportunity for different build layouts and with the size of this, many different builds. The only downside I discovered during my new build was that you cannot remove the hot-swap bays. Other than that, this is an absolutely brilliant case that, for me, will survive multiple future builds!

I run a FreenAS server with 5x8TB hdd. Doing backups via network gets me about 50MB/s. By having the backup disks inside this case I can backup at least three times faster using the internal bus. The design is a bit dated as modern motherboards have USB 3.1 Gen 2 and C. However the large internal size is a treat for indstalling any mobo plus plenty scope to strap the cables neatly. The case has 16 bays; 3 of which is 5.25" and the rest are good for 3.5" hdd. I use one 5.25" for CD rom and the remaining 14 for 3.5" hdd all running 7200rpm. The case has plenty fan connections but with only 3-wire plus separate LED 2-wire connections. However modern fans have 4-wire connectors for speed control and LED. I am not a big fan of LED and in any case most modern mobo can supply many fancy LED control connections. The vast internal space is probably the best setting point as all equipment can cool properly and that is good news for servers or workstation on 24-7 service. With this case there is hardy any compromise in selecting the PC components like type and size of the cpu cooling and length of video card. The backing plate is aluminium which I found rather flimsy, especially if you have to insert DDR4 memory modules into the mobo already fixed in position. The construction overall is the best I have encountered as I have used all the major manufacturers. The two glass swing panels is the best for access into the PC internal parts. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/50632321-cooler-master-cosmos-ii-25th-anniversary-edition-computer-case-xl](https://www.desertcart.vu/products/50632321-cooler-master-cosmos-ii-25th-anniversary-edition-computer-case-xl) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-19*
