Clean lines for a dark-themed build
The black CX300 ARGB is an ATX mid-tower for gamers who want a panoramic glass case that also handles a full-size graphics card. The tempered-glass front and side panels are non-drilled for a clean 270° view, and mesh on the bottom and side feeds a vertical airflow layout with support for up to 10 fans. Four ARGB fans are fitted, three of them reverse-blade fans on the right side and one at the rear. EVA anti-vibration foam on the power supply mount helps reduce resonance, and magnetic dust filters on the top and bottom lift off for cleaning.
Fit notes and the white alternative
Graphics cards up to 420mm, air coolers up to 170mm and power supplies up to 245mm fit, so most high-end parts will go in. If a top-mounted radiator interferes with your memory, RAM height is limited to 45mm, so tall RGB kits are better paired with the 240mm side position or an air cooler. The reverse-blade fans are meant for the right-side position, showing their clean face through the glass. Black suits builds with dark motherboards and cables, where nothing needs to match; the white CX300 ARGB is the alternative for white-themed systems.

Questions
Before you buy
Will my graphics card fit in this case?
It takes cards up to 420mm long. Every graphics card we list shows its length on the Specifications tab, so compare the two numbers and leave a few millimetres for the power connectors. Front-mounted radiators and fans usually eat into that clearance - the case manual will say by how much.
What CPU cooler will fit?
Air coolers up to 170mm tall, and liquid cooler radiators of 120mm, 240mm, 360mmmm. Cooler height is measured from the motherboard surface to the top of the heatsink, and it is the dimension that most often catches people out with a side panel that will not close.
Which motherboards does it take?
It accepts ATX, Micro-ATX, Mini-ITX boards. A case always takes its own size and anything smaller, so there is no harm in fitting a compact board in a larger case beyond a little wasted space.
Is it in stock, and when will it ship?
This one is out of stock at the moment. Stock does come back in - WhatsApp us on 079 491 0181 with the model and we will tell you what the supplier is showing and let you know when it lands, rather than leaving you to keep checking the page.
What does delivery cost, and how long does it take?
We deliver by courier anywhere in South Africa, and delivery is R180 on orders under R2 500 and free on orders of R2 500 or more. It takes 1-3 working days to Johannesburg, Pretoria, Cape Town, Durban and areas within 100km of them, and 2-4 working days to areas more than 100km from a major centre, counted from the day the order is dispatched. Need it sooner? Express delivery is 1-2 working days for R210, or R150 on orders of R2 500 or more - choose it at checkout. We do not ship outside South Africa.
Can I collect instead of having it delivered?
Yes. Collection is from 11 Voortrekker Avenue, Edenvale, Gauteng, by arrangement - message us first so we can have the order picked and waiting. We are open 09:00 to 16:30, Monday to Friday.
What warranty does it carry, and how do I claim?
The warranty period for this product is listed at the end of the Specifications section above. Claims go through us, not the manufacturer - contact us with your order number and a description of the fault and we will handle it from there. Separately from any warranty, the Consumer Protection Act gives you six months from delivery to return goods that are defective, unsafe or not fit for their intended purpose.
What if I change my mind?
You have 14 days from delivery to change your mind - longer than the seven days the Electronic Communications and Transactions Act requires. The item needs to be unused and in its original packaging, and we pay the return shipping. Refunds go back to the payment method you used, within 30 days of the return reaching us.
How can I pay?
Payments are processed by Stitch. At the last step of checkout you are taken to Stitch’s secure page to pay, and brought back here once it is done. Your card details are entered on Stitch’s secure, PCI-compliant page and never touch our systems.
