12 min read5 products evaluated

Workstation cases take E-ATX boards and lots of storage. Every pick supports E-ATX, ordered from the lowest price.

Rankings weigh largest radiator, fans included and motherboards as the makers state them; if a maker skips largest radiator, the guide says so rather than guess, since we have not benched them.

What to Look for in a Workstation PC Case

Key buying criteria so you get the right fit the first time.

  1. How much largest radiator size you need

    Here largest radiator size runs from 360mm on the 3500X to 480mm on the Enthoo Pro 2 Server. The Flux Pro comes second for less money. No figure for the QUBE 540 and the 3500X RS ARGB.

  2. Fit and compatibility

    GPU limit in the QUBE 540: 415mm, before front fans. Confirm GPU length for the 3500X with its maker. Confirm GPU length for the 3500X RS ARGB with its maker.

  3. Extras that separate them

    The 3500X RS ARGB: mounts for up to ten 120mm fans. The Flux Pro: two reverse fans on the PSU shroud. The Enthoo Pro 2 Server: support for 480mm and 360mm radiators and 11 PCI slots.

  4. How much to spend

    $50 to $100 buys the QUBE 540, the 3500X and the 3500X RS ARGB; $100 to $150 buys the Flux Pro; $150 to $250 buys the Enthoo Pro 2 Server at our last check.

  5. Start from what matters most

    Getting horizontal or vertical orientation with a reversible I/O panel for the least money: the QUBE 540. Buyers who want wraparound glass: the 3500X RS ARGB. Buyers who put largest radiator size first: the Enthoo Pro 2 Server.

  6. Plan radiator positions early

    A case may list a 360mm radiator only at the front or only on top. Top mounts must clear the motherboard heatsinks and tall RAM, and front mounts can shorten the GPU limit.

Frequently Asked Questions

Which has the largest largest radiator size: the Enthoo Pro 2 Server or the Flux Pro?

The Enthoo Pro 2 Server leads at 480mm, with the Flux Pro at 420mm. The 3500X is at the other end of this group with 360mm. The QUBE 540 and the 3500X RS ARGB don't state a figure, so they sit outside this comparison.

Why is the Enthoo Pro 2 Server our Largest Radiator Size pick?

It earns the label for the largest radiator size here (480mm). It suits anyone who put largest radiator size first.

Will the 3500X work with my setup?

Confirm GPU length for the 3500X with its maker. The 3500X takes 360mm radiators; mind RAM height. In this guide it ranks second of 5.

What extras do the QUBE 540 and the 3500X include?

The QUBE 540: horizontal or vertical orientation with a reversible I/O panel. The 3500X: mounts for up to ten 120mm fans. The 3500X RS ARGB: three RS120-R ARGB fans on a +5V ARGB header.

Does a glass front make a PC run hotter?

It can, when air has to enter through narrow gaps. Glass-front cases that take air from the side or bottom avoid most of that penalty.

Bottom Line

Our first pick is the QUBE 540, chosen for the lowest price of the group at our last check. Look at the 3500X for mounts for up to ten 120mm fans, the 3500X RS ARGB for wraparound glass and the Flux Pro for a 420mm and a 360mm radiator at the same time if those matter more to you.
