The DeepCool CL660 WH is a split-chamber ATX case that physically separates your radiator, motherboard tray, and PSU into isolated compartments — so heat from one zone never bleeds into another. Available in Bangladesh through CSI, the country's leading IT products distributor, this case is built for builders who want a high-airflow, liquid-cooling-ready chassis without the clutter of a single-chamber layout.
A Case Designed Around Where Heat Actually Comes From
Most ATX cases treat the interior as one open box — your GPU, radiator, and PSU all share the same air. The CL660 WH takes a different approach. DeepCool calls it HyperSplit: a raised top chamber holds the radiator on its own dedicated airflow path, while the main chamber below stays reserved for your motherboard, GPU, and storage. In practice, this means the warm exhaust from your 360mm AIO never mixes with the intake air feeding your graphics card — a detail that matters more as GPUs get hotter and cases get more compact.
What Building Inside the CL660 WH Actually Feels Like
Every panel — front, side, and top — comes off without a screwdriver, which sounds like a small thing until you're seating a 360mm radiator and don't want to fight the case to do it. The PSU sits horizontally at the front rather than the rear, with its cabling facing the back of the motherboard tray, and DeepCool leaves roughly 35mm of routing space behind the tray with Velcro straps and cover plates already in place. First-time high-end builders tend to notice this immediately: cable management that would normally take an hour takes closer to fifteen minutes. A pop-out headset hook hidden in the front bridge and an included GPU anti-sag bracket round out the small conveniences that only show up once you're actually living with the case, not just reading its spec sheet.
Who Should Actually Buy This Case
- Gamers running 360mm AIO coolers who want the radiator's heat kept away from GPU intake air
- Content creators and streamers in Dhaka's home-studio setups who need quiet, sustained thermals during long render or stream sessions
- Builders upgrading from an old mid-tower who want back-connect motherboard support without jumping to a full-tower case
- Anyone assembling a showcase PC where the tempered glass panel and raised-chamber silhouette matter as much as the thermals
Airflow and Thermal Behavior, Without the Marketing Jargon
The top chamber is pre-configured for a 360mm radiator, and the case supports push-pull fan configurations (fan–radiator–fan) if you want to squeeze out extra cooling headroom later. Two reverse-blade ARGB fans are pre-installed at the bottom, pulling fresh air directly toward the GPU rather than recycling warm case air — a layout choice that specifically benefits long graphics cards, which the CL660 WH accommodates up to 388mm. Air-cooler users aren't left out either: there's clearance for coolers up to 175mm tall, which covers the vast majority of dual-tower air coolers sold in Bangladesh today. Seven expansion slots and support for ATX, Micro-ATX, and Mini-ITX boards mean the case doesn't lock you into one platform generation.
Fit, Finish, and Everyday Usability
The white variant pairs a tempered glass side panel with vertical front grille bars, giving the CL660 WH a cleaner, more architectural look than the typical mesh-front gaming case. Front I/O is kept practical rather than crowded — two USB 3.0 ports, one Gen 2 USB Type-C port, and a combined audio/mic jack, all positioned for easy reach on a desk rather than buried on a top panel. Internally, the case takes two 3.5" drives and one 2.5" drive, enough for a boot SSD plus a secondary storage drive without needing a separate NAS or external enclosure for most home and small-office setups.
Why Buy the CL660 WH Through CSI
CSI is Bangladesh's top-ranked IT products distributor, and every DeepCool unit sold on csi.com.bd is 100% genuine, factory-sealed stock — never grey-market imports. That distinction matters with liquid-cooling-capable cases, where a counterfeit fan controller or radiator seal can quietly void your warranty claim later. Every CL660 WH purchased through CSI carries the manufacturer's 12-month limited warranty on the case, backed by CSI's own local after-sales support — so if something needs replacing, you're dealing with a Bangladeshi distributor directly, not waiting on an overseas RMA process. CSI also ships nationwide with secure, tracked delivery, and its sales team can confirm real-time stock and compatibility (PSU form factor, radiator clearance, motherboard fit) before you order — something a marketplace listing simply can't offer.
How It Sits Next to DeepCool's Other Split-Chamber Case
If you want the same split-chamber philosophy but prefer a fully visible, single-chamber "fishtank" build style with front-facing digital display, CSI also carries the DeepCool CH690 Digital Tempered Glass Panels Single Chamber ATX Fishtank Case — a good comparison point if you're deciding between a compartmentalized layout and a panoramic showcase build.

Frequently Asked Questions
What makes the DeepCool CL660 WH different from a standard ATX case?
It uses a split-chamber (HyperSplit) layout that physically separates the radiator zone from the motherboard and GPU zone, preventing warm exhaust air from mixing with component intake air — something single-chamber cases can't do.
What is the maximum GPU length the CL660 WH supports?
The case supports graphics cards up to 388mm in length, covering nearly all current flagship and mid-range GPUs.
Does the CL660 WH come with fans and a radiator pre-installed?
Yes. It ships with two bottom-mounted reverse-blade ARGB fans pre-installed, and the top chamber is pre-configured to fit a 360mm radiator or AIO liquid cooler.
What motherboard sizes are compatible with this case?
The CL660 WH supports ATX, Micro-ATX, and Mini-ITX motherboards, including back-connect ATX boards for cleaner cable routing.
What is the maximum air cooler height it can accommodate?
It supports air coolers up to 175mm tall, which fits the majority of dual-tower air coolers available in the market.
Is the DeepCool CL660 WH sold by CSI a genuine, authorized unit?
