Seem new ### ⭐⭐⭐⭐ Good case *by E***N on 22 February 2025* Good case and very clear instructions however, not good enough screws for a Micro ATX apparently. Only 3 screws of my 8 holes actually screwed in. ### ⭐⭐⭐ Not for first time builders... *by T***O on 12 February 2025* I bought this to replace a fantastic Thermaltake Core v21 as I wanted something smaller. Building in the case is really good, just make sure all your parts fit properly first. The cable routing is great and the build is now a lot neater than previously. The material quality of the case is acceptable, nothing shakes or rattles, but there is some use of plastic on the external corners I dislike. It's also nice that the case can be laid flat on it's side. Cable management is very good. So what's the problem? Simple, not enough air passes through the darn thing because the ventilation holes are too small all round. This means the front fan struggles to feed the gpu the air it needs to remain cool. How much would it have cost to just make bigger holes? I can't recommend this case for that reason alone. I'm keeping the case because I really like it aesthetically, and I will be modifying it, (cutting holes in the front and bottom faces), myself for fun. If you're not up for that be aware that your gpu will run a little hot with the stock case. ## Frequently Bought Together - Cooler Master MasterBox Q300L V2 - mATX Mini-Tower Case, 1 x 120mm Pre-Installed Rear Fan, Tempered Glass Panel, Clean Routing, Multiple Thermal Options & USB 3.2 Gen 2x2 Type-C 20GB/s - Corsair VENGEANCE LPX DDR4 RAM 32GB (2x16GB) 3200MHz CL16 Intel XMP 2.0 Computer Memory - Black (CMK32GX4M2E3200C16) - Crucial P3 Plus SSD 1TB M.2 NVMe PCIe Gen4 Internal SSD, Up to 5000MB/s, Laptop & Desktop (PC) Compatible, Solid State Drive - CT1000P3PSSD801 --- ## 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.nl/products/555309576-cooler-master-masterbox-q300l-v2-matx-mini-tower-case-1](https://www.desertcart.nl/products/555309576-cooler-master-masterbox-q300l-v2-matx-mini-tower-case-1) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-06-01*
