Who it fits
Good fit for
This reservoir suits builders who need a long, narrow tank for tight cases. The 300mm length offers ample space for large loops. You will appreciate the multi-port layout if you have many tubing lines to route. The acrylic material lets you see fluid flow clearly. It fits well in setups where vertical space is limited but depth is available. The 55mm diameter is standard for many G1/4 fittings. This is a practical choice for functional custom loops.
Who should skip it
You should look elsewhere if you need a short reservoir. This model starts at 100mm but you are viewing the 300mm version. The 55mm diameter is wider than some compact options. If you require a smaller footprint, a 50mm variant might work better. The data does not mention integrated lighting. You also get a basic acrylic finish without extra coatings. Avoid this if you want a pre-filled or sealed unit. This is a raw component for your own assembly.
Verdict: The greenDracaena 300mm Acrylic Reservoir offers a durable, long tank for custom loops. Its multi-port design and clear acrylic body make it a solid choice for detailed builds.
Key specs explained
Size: 300mm
This length determines the vertical space required in your case. A 300mm reservoir offers a larger water volume than smaller options, which helps stabilize temperatures in custom loops. You should check your case compatibility before purchasing. This size suits builders who prioritize thermal mass and visual presence over compact footprints. Compare this dimension against your available rack space to ensure a proper fit.
Outer diameter: 55mm
The 55mm width defines the footprint of the reservoir on your mounting bracket. This diameter is standard for many G1/4 port fittings, ensuring broad compatibility with your tubing and adapters. You need to verify that your case has sufficient clearance around this width. This measurement helps you plan your loop layout and avoid collisions with other components or case walls.
Material: Acrylic
Acrylic provides a clear, glass-like appearance for your loop. It allows you to see coolant flow and bubble traps clearly. This material is lightweight and easy to clean. However, it can scratch more easily than polycarbonate. You benefit from the aesthetic transparency. When shopping, consider that acrylic offers a classic look for custom builds, distinct from opaque or metal reservoirs.
Port type: G1/4
The G1/4 thread is the universal standard for water cooling fittings. This ensures you can use a wide range of barbs, adapters, and fittings from various manufacturers. You do not need proprietary parts. This compatibility simplifies loop building and future upgrades. When comparing products, verify that all your fittings match this thread size to avoid leaks or connection failures in your custom loop.
Materials and Physical Build
The listing specifies that the reservoir body is constructed from PMMA, commonly known as acrylic. This material provides the transparent section you see, allowing you to monitor fluid levels and flow clearly. The upper and lower covers are made from POM, which is described as a high-temperature resistant engineering plastic. This combination suggests a design focused on durability and heat management for the end caps, while prioritizing visibility for the main chamber.
According to the listing, the outer diameter ranges between a minimum of 50mm and a maximum of 55mm. The specific model you are reviewing has a 300mm total length. This dimension dictates the vertical clearance required in your computer case. You must ensure your chassis has sufficient height to accommodate this length without interfering with other components. The width and length dimensions are both listed as 1.97 inches, which aligns with the 50mm to 55mm diameter range.
The product is available in multiple sizes, including 100mm, 200mm, and 300mm options. The 300mm version offers the largest footprint among these choices. This size choice impacts the overall volume of coolant held, which can influence thermal stability in your loop. The build uses G1/4 threading for connections, a standard fitting size. This ensures compatibility with most common tubing and fittings used in custom water cooling setups. The design is straightforward, relying on the material properties rather than complex electronic controls or displays.
Setup And Everyday Use Guide
Installing this reservoir requires careful planning regarding physical dimensions. The 300mm length demands significant vertical clearance in your computer case. You must verify that your chassis can accommodate a unit with a 55mm outer diameter. The listing notes that international products may have different labeling or instructions. This means you should read any included documentation carefully before beginning assembly. The G1/4 threading is standard for most custom loop fittings. You will need compatible tubing and barbs to connect the inlet and outlet ports. The multi-port design allows for flexible plumbing arrangements. You can route lines from different angles without complex adapters. The PMMA acrylic body is transparent. This feature lets you monitor fluid levels and check for air bubbles during the fill process. Daily use relies on the stability of the POM caps. These high-temperature resistant engineering plastics provide a secure seal. They help prevent leaks during normal operation. The larger water volume associated with the 300mm size helps stabilize loop temperatures. This thermal mass reduces rapid temperature swings when your system workload changes. You do not need to add fluid frequently if the loop is sealed correctly. The clear acrylic allows you to see the coolant color and cleanliness. This visual feedback is useful for routine maintenance checks. You can spot debris or discoloration early. Ensure all fittings are tightened properly to maintain integrity. The straightforward design means you spend less time on complex mounting brackets. Focus on proper tubing routing and leak testing before powering on your system. The physical build supports long-term reliability in a custom loop environment.
Before You Buy This Reservoir
You need G1/4 fittings for all connections. This reservoir uses standard sizing, but you must buy fittings separately. Ensure your tubing inner diameter matches your fittings. The 300mm length requires significant vertical space. Check your case internal dimensions carefully. You may need longer standoffs or a different mounting position. The acrylic body needs gentle cleaning. Use only soft cloths and mild soap. Avoid abrasive materials that scratch the surface. Dust accumulation is common. You will need to clean it periodically to maintain clarity. This product fits into custom loops, not pre-built AIOs. It is for builders who want visible fluid levels. Compare it with other 300mm options if you need more volume. Smaller sizes save space but hold less coolant. This unit suits those who prioritize aesthetics and thermal mass. Verify thread types before ordering. The caps are POM plastic, which is durable. Ensure your pump fits the inlet port. Plan your loop layout early. This reservoir is a core component, not an add-on.
Check before you buy
- Verify your case has enough vertical clearance for the 300mm length.
- Confirm you have compatible G1/4 fittings and tubing for connections.
- Check if your pump head fits the reservoir inlet port.
- Ensure you have mounting hardware suitable for your chassis.
- Decide if the larger volume suits your loop's thermal needs.
