Review: Best for compact purposes. will fit big luggage for check-in. - While nothing is really perfect, this modular case lets you style give you a lot of options for your PC. Small form factor case for your mATX (perfect fit) and ATX (pushing it a bit but still okay). Can accommodate long GPUs. You have the liberty to fix CPU components (PSU, Fans, I/O Panel) as you like. Cooling is a bit tricky but should be fine after a few arranging of parts which i totally love about it. I enjoyed arranging components to get where i wanted. Plenty of wire routing options which are stealthy for a cleaner install. While cooling takes a bit effort compared to mid-tower/full towers, Im sure this will accommodate more cooling parts and be way cooler than your regular small form factor ITX cases. will buy another one for a future project if needed.
Review: الصندوقQ500l شكله جميل واماكن تركيب الكابلات فيه جيدة لقد قمت بتركيب لوحة ام من نوع micro ATX ولم اواجه اي مشكلات في التركيب و المروحة الخلفية صوتها منخفض وجودتها ممتازة ، ولاكن مكان وضع مزود الطاقة موجه الى الواجهة الامامية للصندوق فسوف تسمع صوت مروحة الباور سبلاي فقط اذا كان صوتها عالً اما اذا كان منخفض فلابئس بذلك، انصح بشرائه بهذه السعر.
