The distinctive variety of PC case worth contenders we’ve reviewed within the 12 months since we reviewed Montech’s Air 903 Max has given us an opportunity to rethink its design—and that of its base-model sibling, the 903 Base, that we had been despatched for assessment. Is the cheaper Air 903 Base entry-level mannequin a greater worth than the Max, an Editors’ Alternative award winner? The large distinction between these two low-cost chassis is the shortage of RGB units within the 903 Base, however the characteristic set isn’t in any other case all that a lot lighter for this $64.99 mannequin. Should you’re all in regards to the utility and fewer in regards to the lighting, the 903 Base trumps its $79.99 predecessor as a no-frills low-end case for price range builders nonetheless trying to go “massive rig.”The Design: Lightness UnlitIn addition to it not having the lighted followers of the Max model, the Air 903 Base has one fewer fan and no fan hub. That final half makes some sense to forego, for the reason that hub of the Max model supported each the PWM and ARGB connectors of its ARGB followers. (The wiring is half as difficult with Air 903 Base’s followers.) Plus, the Base model nonetheless offers us the see-through mesh face of its pricier counterpart.
Since 1982, PCMag has examined and rated 1000’s of merchandise that can assist you make higher shopping for choices. See how we check.
The one drawback with eradicating the fan hub is that its ARGB hub additionally had its personal ARGB mode controller and a mode-selector button. That button (“LED”) turns into vestigial on the Base mannequin, although different options just like the backlit energy button, the twin USB 3 Sort-A ports, the Gen 2×2 Sort-C port, and the separate headphone/microphone audio jacks all proceed to perform usually. The additional button places the 903 Base reverse fashions that use repurposed reset buttons to function their guide ARGB controllers.

Round again we see a normal (inset) I/O panel and a 140mm exhaust fan, the latter sitting on a set of screw slots that permit adjustment of round an inch upward. The inset I/O panel is the half that places Montech far forward of a number of budget-case opponents; the flush panels utilized by a number of of its pricier opponents are cheaper to fabricate however more durable for builders to make use of.

The underside rear fringe of the Air 903 Base includes a slide-out mud filter that’s simply sufficiently big to serve the ability provide inlet, and nothing else. The remainder of the case makes use of mesh panels to entice mud, which implies that the entrance panel will gather it rapidly if utilized in a dusty setting. Be prepared with a rag.

The Air 903 Base is designed to carry as much as 12 motherboard standoffs and helps the total 13-inch-deep Prolonged ATX (EATX) motherboard specification, the place two bumps close to the entrance of the motherboard tray are designed to carry the entrance/middle standoff of such oversize boards. The eight rubber grommets in the identical space are spaced to carry 2.5-inch drives, together with notebook-size arduous drives and SSDs.

A canopy over the ability provide bay, connected to the motherboard tray’s decrease edge, options two 120mm fan mounts, 4 cable passages, and a 60mm-deep front-panel radiator hole. Although radiators as much as 460mm in size will be positioned vertically behind front-panel followers, the necessity to tilt radiators into that gap from beneath the case’s fastened prime panel limits the thickness of such lengthy radiators to round half that quantity.

We once more see the units of 4 grommets that align to 2.5-inch drive mounting holes with the case flipped round, however we additionally see two detachable 2.5-inch trays and a 3.5-inch drive cage, that final half full of a boxed {hardware} accent pack. Although your entire entrance panel is detachable, those that would moderately simply take away the metallic insert will discover that doing so offers full entry to the case’s entrance fan mounts.

A better have a look at that 3.5-inch drive cage reveals that it’s drilled to carry a further drive on prime, and that it suits onto one in all two optionally available mounting positions on the backside. Two units of holes on the highest are designed to suit both a 3.5-inch or 2.5-inch drive. As for the 2 mounting positions, they supply both 270mm of energy provide house with 35mm of radiator house, or 240mm of energy provide house with 60mm of radiator house. (Leap again two paragraphs to see why it’s merely not 65mm.)

For these not happy with the entrance radiator house, Montech supplies sufficient room on the highest panel to carry a 360mm-format radiator (as much as 396mm lengthy), or a 280mm-format radiator if you happen to’d like one thing a bit shorter and wider. The broader radiator will crowd the board, because the 40mm to 45mm of horizontal offset from the motherboard’s floor is decreased by 20mm when utilizing followers which might be 20mm wider. And that’s most likely going to be essential in your construct, for the reason that prime fan mounts sit solely 57mm above the motherboard’s edge.

Some extra fitment enjoyable! Customers of 420mm front-panel radiators will discover that their prime panel house is decreased by the thickness of their front-panel radiator, and customers of 360mm top-panel radiators will discover that the peak of their entrance radiator have to be decreased by the thickness of each any radiator and any followers on the highest panel. In the meantime, reaching these pesky EPS12V connectors on the prime of your board with a 280mm radiator in place will most likely require you to slip that radiator all the best way ahead, whereas mounting a 420mm radiator up entrance will seemingly require you to maneuver that very same radiator backward. Thus, the most important sensible configurations are two 360mm or 280mm format radiators, although a 420mm entrance/280mm prime combo is probably going attainable for these with sufficient dexterity and endurance. After all, if you happen to’re shopping for that many radiators, and cooling that hard-core a rig, you might be most likely spending greater than $65 in your case. Or ought to be!Constructing With the Montech Air 903 BaseThe Air 903 Base consists of the whole lot that the majority builders might want to fill their circumstances, together with the three additional standoffs for 13-inch-deep motherboards and the shoulder screws that permit mounting 2.5-inch drives onto the motherboard tray’s grommets. Although we’ve grown accustomed to considering of two.5-inch drives in desktops as traditional SSDs, these vibration-damped 2.5-inch drive mounts harken again to the times of WD’s high-speed VelociRaptor platter arduous drives.

The Air 903 Base’s front-panel LED and swap group is break up right into a separate group for the lighted energy button and reset swap. The HD Audio jack feeds separate headphone and microphone jacks, the 19-pin USB 3 connector feeds the 2 Sort-A ports, the Gen 2×2 (Sort-E) connector feeds the highest panel’s Sort-C port, and a two-fan splitter cable is manufacturing unit linked to the 2 entrance fan cables. As for the ARGB controller lead, inventive concepts for repurposing which might be yours alone.

Mounting our radiator above the motherboard’s CPU voltage regulator doesn’t appear to be the perfect answer for low CPU temperatures, however we’ve discovered that the advantages to voltage-regulator temperature far exceed the deficits in CPU temperature. Since this configuration additionally permits us to check the Air 903 Base with all three of its followers within the manufacturing unit positions, everyone wins. We’ll try this.

Particular to at this time’s check of the Air 903 Base is the three inches of house between the entrance of PNY’s huge RTX 4070 Ti and the case’s entrance panel. We’d wish to say that it seems to be pretty good, however we’d moderately allow you to be the decide:

And right here we have now a abstract of our normal testing components loadout…
Testing the Montech Air 903 Base: Low cost Cool, Not So QuietThe Air 903 Base’s massive entrance followers present a giant increase in airflow, dropping the temperature across the higher rear nook of our motherboard sufficient to place it within the lead for each CPU and voltage-regulator cooling efficiency on this comparability set. It additionally drops to fourth place in GPU cooling, however we understand that air flowing in a single a part of the case won’t be as helpful in one other.
The large cooling offered by these massive followers additionally got here with a giant noise quantity: Although the numeric distinction isn’t very giant, the decibel scale is logarithmic, in order that an SPL distinction of solely 3db represents an audible distinction of round 30%.
Verdict: Too Huge a Funds Worth to IgnoreIs the 903 Base a straightforward case to go over if you happen to’re it on a shelf filled with different chassis, in isolation? Certain. With out the RGB bling of its 903 Max kin, it’s a fairly nondescript effort in inventory type. However have a look at the value tag, and you might rethink.Should you’re a function-over-form PC builder, the Air 903 Base offers you lots of flex in putting in liquid-cooling gear on a budget, releasing up more cash for an additional radiator, higher followers, extra RAM, or perhaps a leveled-up GPU or CPU. And actually, for fanatics vying to get essentially the most from their DIY greenback, it’s that leveling up that counts most. It’s not a horny glass aquarium case or a slick aluminum effort, however name the Montech Air 903 Base the budget-strapped fanatic’s greatest buddy.
