FSP has announced two new mid-tower cases: the FSP CMT330 and the FSP CMT520. The two new cases feature FSP’s “halo cover” mirrored floor plate which sits on top of the power supply cover, and the same interior, but are styled quite different on the exterior. The CMT520 has the more premium look of the two and includes glass front and side panels as well as an integrated LED and fan controller. The CMT330 uses an acrylic side panel, no glass front, and adds support for 5.25-inch drives. Both mid-tower chassis are targeted gamers and enthusiasts who would like a premium look at an affordable price point. 

The exterior of the CMT520 does have a more premium appearance to it with its glass side and front panels allowing an unfettered view of the hardware inside the case. Though there isn't as much glass as the CMT510 with three glass panels, the CMT520 offers a full view of the parts many want to show off. The 520’s I/O panel is also at an angle between the top and front of the case. Both of the chassis use upgraded front I/O panel that consists of two USB 3.0 ports, two USB 2.0 ports, a power button, and microphone and headphone jacks (no USB 3.1 Type-C or Type-A). The front of the 520 holds three RGB LED fans as well as another on the back panel (all four included) sending air through the interior and out the back and top. The fans and RGB can be controlled through an integrated controller and is compatible with existing RGB LED ecosystems from major board partners.


When talking about the CMT330, it does add a bit of flare and includes a blue LED light bar at the bottom of the case. Also included are three 120mm fans, one of which is a blue LED fan found pre-installed in the rear of the case adding to the blue glow the case will have. With the acrylic side panel and solid front panel, it does look like a more standard case than its bigger brother. 


The interior of both mid-tower cases are able to support a maximum CPU cooler height of 163mm and video cards up to 423mm in length. For cooling, both chassis support up to 3x120mm radiator up top, 120mm on the rear, and 3x120mm on the front. Motherboard support ranges from Mini-ITX up to ATX (520 shows E-ATX compatibility) so both cases have a lot of flexibility in that regard. Both have room for two 3.5-inch HDD and four 2.5-inch SSDs while the CMT330 has the ability to house two 5.25-inch ODDs in addition to the 2.5/3.5-inch spaces. Note in the case of the CMT330, installing something in the 5.25-inch bays will limit the number of front panel fans to two. The halo cover on both chassis have a reflective panel designed to reflect any lighting inside the case, and the cover held in place by magnets.

    no built in vertical GPU mount (yes you can mod it) but it would have been nice if they included it. The TT view 31 which is very similar has this (but no PSU shroud). The CMT520 looks nice. Reply

    The point of that would be.... what again?

    My immediate issue is lack of bottom intake fans. Oh and I didn't see anything in the article about intake fan filters, I no longer buy anything without filters (for myself or family anyway).

    Again, as usual by companies going for form over functionality, there is utter lack of adequate spacing for intake air flow. These would be great cases if it weren't for that critical flaw.

    Cooler Master got some feedback about this on their Master Case H500P and subqeuently release an airflow enhanced edition, the H500M with front mesh grill instead of near total complete plastic covering (like these).

    One Canadian hw review youtuber Gamers Nexus tests all the cases with front cover on vs cover off and in every single one without exception, the ones with the obvious blockages like the CM one and these have abysmall cooling in a typically configured system under load with cover-on compared to cover-off. Example:

    In you can even perform a simple air flow test yourself: tape a light piece of paper on top of the front intake fans and see how much it lifts with cover-on vs cover-off. It really makes me wonder if any of these companies even perform basic air flow tests at all.

    The only companies I see that hasn't succumbed to such foolery is Fractal Design and Nanoxia

    I like Fractal and will probably get a Define R5 for my next built. But with that being said, I can't STAND mesh front covers. I want a solid cover... but they need to have adequate space for air to flow around the cover. From what I can tell the R5 seems to handle this well enough for its twin front intake fans, especially at the relatively low RPMs I am going to be running. The bottom fans also seem to have enough of a gap thanks to the solid-looking feet. Reply

    The R5 should be great. I have the R3 and just got the R6. Clear cases with solid front covers need big spacing like the Corsair 400C or 600C (460X is good but not great as the gap is reduced)

    Ironically fan noise is actually a bit worse with a cover on at low rpms due to have extra vacuum and forced redirection of airflow. I found this out for myself with various cases (and just experimentally putting obstructions in the intake side vs exhaust side) and Gamers Nexus saw that noise difference as well.

    Exactly, especially if you're interested in quiet/silent operation. It's definitely a balancing act: you want good air flow to keep components cool with fewer and lower speed fans, but you also want as few direct paths for noise to escape as possible. Reply
