Inside The 400R
Corsair's 400R supports up to six hard drives on removable trays, in addition to four 5.25” external drives.
From this angle, we can also see part of the 120 mm bottom intake fan mount, located a couple inches forward from the power supply’s intake vent.
400R Intakes
LED backlighting on the 400R’s twin 120 mm intake fans adds some flair, though a switch on the case’s front panel lets you turn them off if you want.
Atop The 400R
Corsair designed its 400R to support two 120 or 140 mm fans, spacing both sets of holes appropriately for dual-fan radiators.
Yet, with only 1.3” of clearance in both directions (above and in front of the board), you might find it difficult to mount anything thicker than a pair of fans there. We suggest checking your motherboard for DIMM and sink clearance before attempting to pair this case with the firm’s Hydro H100 kit.
400R Cable Management
A moderate amount of motherboard tray offset complements the 400R’s larger side panel, creating lots of hidden space for cable routing.
400R Filtration
An extra-long dust filter on the 400R’s bottom panel covers its optional intake fan mount, as well as its power supply intake fan. It slides easily out the case's rear edge for cleaning.
The 400R’s front panel also has filter mesh, though it’s not as easily removed.
In Win Buc
At least from a marketing standpoint, In Win seems to be two companies. Its Web site is split between stodgy office-oriented products and its newer In Win Style brand.
Deep contours and mesh panels classify the Buc as one of In Win's Style cases, though a centrally-located 3.5” external drive bay harkens to the company’s past. We like that touch of tradition, since we still own a few 3.5” bay panel devices.
Eight holes on the mesh side panel allow builders to add two 120 mm fans, if they choose.
Buc Ports
In Win adds a handy storage tray atop the Buc, but complicates the use of that tray by mounting two USB 3.0 ports inside of it (presumably to be used by devices sitting in the tray). Other connectors are found on the enclosure's front panel, though. Color us confused by this design decision.
Behind In Win’s Buc
Sliding the Buc’s side panels back an inch or so allows them to be lifted off. Plastic pegs prevent the side panels from sliding accidentally. Instead, they're extracted by lifting the edges of tabs on each panel. If you want to lock the panels down even more securely, In Win drills screw holds near each of those plastic tabs.
Two grommeted holes along the top of the Buc’s rear panel support external liquid coolers.
Inside The Buc
The Buc provides five hard drive trays, in addition to four 5.25” and one 3.5” bay. Devices populating those spaces are secured via push-in pins.
Screw-less card latches for the Buc’s seven expansion slots are also visible in this shot. Screw holes offer additional security, if you need them.
Buc Cable Management
Space between the Buc’s motherboard tray and right side panel is barely adequate for small cables. A vertical channel between the tray and drive bays creates some room for the main power cable, though the hole you see at the very top isn't large enough to pass an ATX12V or EPS12V connector through it.
In Win adds backplane connectors to four of the case’s five 3.5” hard drive trays, and each tray is designed with offset 2.5” mounting holes to assure proper positioning of both drive sizes.
