Nice and compact, very configurable, and has some clever organising feature, eg. SSDs are screwed onto a removable panel on the underside of the main chassis, and then the panel is screwed back into place, allowing the drive to hang on there out of the way. I wasn't sure about the location of the handles because of weight distribution, but the quality of them makes up for any worries I had - they feel very sturdy and they're coated with thick rubber which provides excellent grip and is very comfortable to hold onto. You can orient the box any way you like - the four handles act as sturdy feet and the side panels both have thumbscrews which double as feet as well. The whole thing feels sturdy and like it's made of good quality materials.The only downside to this case for me was that I overestimated the size of my new mini-ITX motherboard, having never had one before, so actually this case was a lot bigger than I needed it to be, being able to accomodate a much larger micro-ATX motherboard (and plenty of other components in space I'm not using), but given how useful its features are I'm happy with it regardless. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Cool case *by C***5 on Reviewed in the United Kingdom on 22 September 2018* Great case, scratches easy, good cable management in back, ### ⭐⭐⭐⭐ 4.0 out of 5 stars smart looking, a bit cramped *by R***S on Reviewed in the United Kingdom on 2 October 2018* it's a very smart case, really nicely laid out internally, the rgb on the top is nice but I can't work out where to plug the front fans in to get them working. also a bit cramped internally but I should have considered my massive high quality motherboard and power supply trying to cram in. --- ## 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.nz/products/59135415-cooler-master-masterbox-q300p-black-mini-tower-case-m-itx](https://www.desertcart.nz/products/59135415-cooler-master-masterbox-q300p-black-mini-tower-case-m-itx) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-04-26*
