Atop The Ravager
Though the Ravager’s top panel supports up to two 140 or 120 mm fans, it lacks the space to mount fans and a radiator.
As a result, our concerns that the fan hole spacing is improper for production liquid-cooling radiators doesn't really matter.
Raidmax Seiran
The second Raidmax case in our 15-way round-up, the Seiran offers far smaller dimensions that more easily fit on top or underneath your desk. Its front-panel ports are also moved forward to allow easier reach from below (sitting on a desk) without significantly impeding access from above (when it rests under a desk).
A 180 mm fan fills a vented side panel that alternatively supports dual 120 mm blowers.
Seiran Ports And Controls
The Seiran’s front-panel I/O is a little more extensive than rival products, adding three-output fan speed and fan lighting brightness controls. Raidmax also includes a single 3.5” bay adapter, with its face plate screwed to the adapter tray.
The case does, however, come up a little short on USB 3.0 connectivity by only giving us one port. Fortunately, dual USB 2.0 ports support more devices, albeit at lower data rates.
Fan control also comes up short, since the rear fan uses a different style of power connector.
Behind Raidmax’s Seiran
Grommets on three ingress/egress holes protect external liquid cooling setups, though running tubes through them will make it harder to get at installed graphics cards.
A c-shaped bulge on the Seiran’s right side-panel creates more room for cable management within an otherwise-compact space.
Inside The Seiran
Nine externally-accessible (and no internal) drive bays simplify the Seiran’s interior, allowing anyone with an extra-long graphics card to run that extra length through the cage itself.
The comparison chart in our upcoming performance analysis makes clear that the case does support internal drives, since the company includes seven adapter trays.
Seiran Cable Management
If you choose the Seiran, expect to get creative with cable management, since the stow area is mainly limited to the c-shaped protrusion on the side-panel. Cable ties come in handy here.
Raidmax leaves the bottom access hole open, while grommets on two narrower cut-outs along the motherboard tray’s front edge help hide cabling mess. The Seiran does not, however, have a pass-through-point for ATX12V/EPS12V cables. As a result, it's almost impossible to use the top of the side-panel's protrusion.
Seiran Drive Mounting
Held in place by twist-on pin connectors, the Seiran’s drive trays serve multiple functions. Brackets on the intake fan are secured to them, firstly, as is the 3.5” face plate for front-panel access.
If you need extra cooling for a particularly hot disk, you can add a 120 mm fan to the tray's outer holes. Notebook drives and SSDs attach to the closer holes. And 3.5” drives are screwed to holes on the side.
Seiran Intake
Though the face plate is not designed for easy removal, most of the Seiran’s front is accessible by removing 5.25” bay covers. Adapter trays are easily accessed, along with a lighted front fan that’s attached to those drive trays.
Seiran Dust Prevention
Though the intake fan relies on open-cell foam backing for filtration, power supply fans are more easily kept clean by a filter sheet that slides out from the Seiran’s rear edge.
We hope that illustrating the extended features of the last five enclosures in our 15-case round-up has piqued your curiosity about their performance. Our upcoming comparison will demonstrate how well each of these cases holds our components, in addition to their heat and noise reduction.
