Fantastic MATX case
The design of this case is great. It is well thought out and very easy to work with in it. Built in cable routing and snap on panels are most welcome.

Great Build
I upgraded from a JONSBO C6 case to the H3 Flow. I've been looking forward to it for a long time. It's great, quiet and cool. I love it.

Frequently Asked Questions

Can I vertically mount my GPU?

The H3 Flow only has 4 PCIe slot brackets, so vertical GPU mounting is not supported.

Are they compatible with Micro-ATX back-connect motherboards?

Yes, the H3 Flow works with back-connect boards from major brands like MSI and ASUS. Just note that some thicker cables may require tighter bends—using flexible cables and taking your time with cable management can help.

Are there any removable dust filters?

Only the top of the case features a removable mesh panel for easy cleaning. Instead of traditional dust filters, the case utilizes perforated panels that provide excellent airflow while helping keep dust out — reducing the need for extra filters.

What is the difference between the H3 Flow and the H5 Flow?

The H3 Flow is a smaller version of the H5 Flow, designed for micro-ATX motherboards with added support for back-connect motherboards. Here’s a look at their dimensions side-by-side:

H3 Flow: 400 mm x 225 mm x 389 mm | 4.8 kg
H5 Flow: 465 mm x 225 mm x 430 mm | 7.28 kg

What should I know before installing an SSD in this case?

There’s an SSD mounting point on the back of the motherboard tray. If you’re planning to use it, it’s best to install the SSD before mounting your motherboard. That way, you’ll have easier access and smoother cable management.
