Pros: - Solid construction - Short depth (17.5" will fit in 20" racks) - Easy enough to disassemble with a phillips head screwdriver - Plenty of space to work with - vibration dampening rubber grommets for cage mounts. - 5x internal 3.5" drive mounts 4 of which are in a drive cage behind the buttons in the front alternatively you can mount an additional 80mm intake fan here, but not both the fan and drives. the additional 3.5" drive mount at the bottom of the 5.25 bay cage. If you order a second drive cage that makes 6 internal mounts and 8-10 hot swap bay mounts for a total of 14-16 depending on the hot swap cage you order. This means the case is pretty good for a short depth high-density NAS enclosure.
Cons: - usb 2.0 front panel headers - Cable management options/mounts are non-existant. You'll probably want to pick up some zip-tie adhesive mounts. - You know how you don't read manuals unless you get stuck or are unsure about something? This doesn't come with one. That made figuring out disassembly and odd mounting an interesting experience the first time around. - Return shipping is half the price of the product, While it's solidly packaged and you shouldn't expect damage- be careful you don't need to return one that you haven't opened yet- it's not worth the cost to do so. - If you want any additional details about the chassis not already on the manufacturers website expect chenbro support to be entirely useless.
Overall Review: So there are some additional things you should know about this chassis - While not listed anywhere- the max supported CPU Cooler height is effectively 160mm. This means an NH-D15(165mm with fans) or Dark Rock Pro 3 or 4 (~163mm) will not fit. You should be ok with smaller high capacity air-coolers like NH-D14 (160mm), NH-U12A(159mm) Scythe Mugen 5, or any smaller CPU cooler. - Also not listed anywhere here or on the manufacturer site is the height of the slim ODD slot. It'll fit 12.5mm drives. If you use 9.5mm ultraslim drives you'll have an unsightly gap. You'll probably also want to pick up a slimline sata to sata adapter cable while you're at it. - You can swap the 5.25 drive cage position and/or order another one to put a second 3x 5.25 hot swap bay in. Doing so will require a Torx 20 driver to remove and rotate the mounting plate. You cannot however swap the 120mm fan cage to the right side, so don't expect to order two of these to have one build with two 120mm fans and another with two hot swap bays. - The 120mm front fan cage does have a filter, but it's not particularly high quality. - When mounting the slim ODD there is a metal bracket you affix to the shallow side of the drive with 2 screws and secure to the chassis with one screw (bag should be labelled) - these screws are probably much smaller than what you're used to when it comes to chassis screws, be sure to have a magnetized screwdriver.
