A panoramic enclosure can look roomy while leaving a tight space around one crucial component. Formula V Line Crystal Z3 deserves an early power-supply check: the official table lists a 140 mm limit including cables. That is a more useful starting point than selecting fans to match the glass.
Quick Answer
Plan the PSU and its installed cable space first, then check the exact Z3 or Z3 Plus package. The Plus version includes three PA2ARGB PWM fans; the base version should not inherit that claim. For a separate local reference, the Antec C2M Black case was listed at R899 on 29 October, not as a Crystal Z3 quotation.
🔋 Read the power-supply note literally
The manufacturer's table says 140 mm including cables. Do not compare that with the PSU body's length and assume the remaining cable arrangement will take care of itself. Identify where the connectors sit, how the cable exits and what clearance the assembly needs. If the planned combination cannot be confirmed, choose another suitable component rather than forcing the connection into a tight bend.
Cable routing should be considered before the motherboard and graphics card occupy the available space. Make a simple parts list with dimensions and connector positions. Browse mid tower cases with those constraints in hand. A case that accepts your board size can still be the wrong choice for the power supply you want to reuse.

🌀 Cooling positions interact with other parts
The specification lists a 360 mm top radiator, a 180 mm CPU-cooler clearance and support for large graphics cards. These are maximums for particular dimensions, not proof that every combination fits together. Check radiator thickness, fan depth and the position of the motherboard's upper connectors in the planned build.
The removable bottom fan bracket can make installation more accessible. It does not establish the temperatures or noise level of your chosen hardware. Keep the air path clear and plan filter access once the computer is on the desk. A build that is easy to maintain is more useful than one that requires removing several unrelated parts to clean an intake.
🎨 Separate orientation from the required accessories
The rear PCIe bracket rotates 90degrees. That supports different GPU presentation options, but the bracket is only one part of a vertical arrangement. Verify the riser requirement, graphics-card position and cable connection before spending on matching accessories. Product photographs are layout references; the manufacturer explicitly directs buyers to the specification for the actual configuration.
The 425 mm graphics-card clearance is worth checking against the complete selected card. Include the space needed for its power cable and the position of any adjacent cooling hardware. Do not treat an orientation shown in a promotional image as evidence that your own card and cooler will have the same room.
🧰 Price the exact version and the whole build
The Plus version's three included fans matter when comparing complete cooling costs. Record the exact version, colour and included equipment in your shopping notes. That prevents a cheaper base enclosure from appearing equivalent to a package that already includes parts you need.
The R899 Antec reference is another chassis with a different layout. It establishes local budget context, not equivalent dimensions or features. If the board is smaller and desk space is the priority, compare mini-itx & micro-atx cases as a separate route. Choose an enclosure after confirming the parts, rather than buying a display layout first and trying to make the hardware fit later.
Frequently Asked Questions
Do the Z3 and Z3 Plus include the same fans?
No. The official page assigns three included PA2ARGB PWM fans to the Plus version.
What is the listed PSU limit?
The specification says 140 mm including cables. Check the complete installed connection space.
Can the GPU mounting orientation change?
The rear PCIe bracket rotates 90degrees for horizontal or vertical arrangements.
Is a riser cable included?
Do not assume one is included. Verify the exact package before planning vertical mounting.
What motherboard sizes are listed?
The range supports ATX,Micro-ATX and Mini-ITX motherboards.
Is the local R899 case the Crystal Z3?
No. It is a separate Antec C2M listing used only as a South African component price reference.
Planning a glass-side build?
Check the installed PSU, cooling and graphics-card dimensions before choosing your exact case package.
