The redesigned 4U server case incorporates high flexibility and high availability to fit most rackmount server case needs. It can be used as a high density raid storage system, data center server, or for high performance supercomputing. Three fans provide the ultimate cooling performance for superior sever stability. Other amazing features include an easy-to-open top cover design, lockable front panel, washable filter, additional frontal USB slot, fan mount, and optional fan sensor board.

  • newegg Front bezel Key lock feature This rackmount comes with an additional security feature that adds a ventilated front cover for your rackmount. The lockable front bezel comes with two keys that utilize a turnkey latch that can lock the front to keep unwanted users from making any modifications to the rackmount.
  • newegg Great Compatibility Having extra depth and space makes it easier for this 4U to include all high-end components users need. Besides support for a MicroATX/ATX motherboard, it offers three 5.25”- and one 3.5” external drive bays, and up to three 3.5” internal drive bays. Additionally, this chassis also adds seven low-profile slots for all PCI-E hardware, so system builders can add other additional components for an upgrade.
  • newegg Ball Bearing Interior Intake Fans The RM-4U4038B48 incorporates two 80mm fans and one 120mm fan to keep your server cool. These fans bring cool air from the exterior of your server, and use it to provide cooler air for your system.
  • newegg Filter Cleaner This rackmount includes an easier way to clean up gathered-up dust and dirt that may hinder your server tower. The filter is strategically placed in front of the dual fans, just behind the front bezel of the rackmount. It reduces cleanup time and any messes that may gather in the rackmount; the filter is also washable.

4 out of 5 eggsGood, but could be better

Pros: it works, space is managable... room for many 3.5 drives.

Cons: Plan on buying a PSU, the stock is only 480w, the connections are as follows: 24pin MB, 4pin CPU, 2 x sata, 4 molex, 2 x 6pin pci. 4pin floppy. stock fans are nice, but you have to work with the molex connection pins to stay put.

Other Thoughts: overall, nice, not awesome, just nice.

1 out of 5 eggsRackmount Shmrackmount

Pros: No pros - just so many cons I actually needed the extra 3000 characters provided by this feedback field.

External issues:

1) Has only front brackets for rack mounting, 2 holes on left and right. Sports rails on left and right that would very neatly fit into a rackmounted slot - but the slot is not provided.
1.a) As shipped, this 35lb hunk of trash is NOT rackmountable unless you're OK with it heinously unbalancing the rack and/or twisting its own mounting brackets and/or laying the rack over on its back every time you go to mount or unmount it.
1.b) I'm going to have to rig something just to get this monster to sit on the rack with something resembling a sane dispersement of weight.

2) Contains NO MANUAL explaining what some of the spare parts the chassis ships with are for or how to use them.

3) There's a secure locking panel on the front of the chassis, which protects the power and reset switches, hides the power and HDD lights, and would prevent the CD-ROMs from opening if triggered by software. The secure locking panel on the front does not protect the power cord, power supply killswitch, or any cable connectors in the back and the secure locking panel does not protect the 2 external USB ports on the front. So the only thing the secure locking panel actually does is prevent anyone turning the server on, which is the only thing I would ever want someone who isn't me to be able to do.

Cons: Internal issues:

1) Standoff positions on the mounting plate are fine for ATX mobos if it was good enough for the standoff positions to be relative to each other - in other words, the standoff holes are spaced perfectly to fit an ATX mobo, but once mounted to standoffs my Foxconn ATX mobo doesn't quite reach the aperture where all the handy little connectors poke out the back. So yeah, it fits an ATX mobo and no, it's not well designed.

2) 480w power supply included with case is worthless.
2.a) Has only 1 4-pin CPU connector. On the other hand, the power supply does have 2 6-pin PCI-E power connectors if you're looking for a rackmount chassis to house your next big gaming system with SLI (and ATA drives...).
2.b) Has only 2 SATA power connectors. That's 2 SATA power connectors - in a chassis that boasts 3 bays for 5.25" internal drives with external access, 1 bay for an internal 3.5" internal drive with external access, and 6 bays for 3.5" internal-only drives.
2.c) Had to replace with a power supply off the shelf just to get my quad-core CPU (requiring both 4-pin CPU connectors) and 3 internal SATA drives powered.

3) Internal fans provided with system are absolute trash.
3.a) The conductive pins in the plastic plugs actually aren't attached or stabilized in any way, so that the conductors retreat out of the plug when you try to plug something into it.
3.b) Not a single case fan even has a mobo jack as an option - you know how modern mobos offer half a dozen fan jacks that don't just power the case fans but also monitor them to report failures? This manufacturer never heard of that.
3.c) Had to secure conductive pins in plugs with super glue just to get them to plug in.

4) This one's kind of petty and maybe (like all the 4-pin ATA-style power connectors on the included power supply) it just points to the fact that this chassis has just been sitting warehoused too long: The power LED connector from the front panel takes up 3 pins - I don't even have a mainboard that provides more than 2 pins. Fortunately it's a standard mobo plug so I was able to move the hot pin to the center hole, and just as fortunately the power led pins on the mobo front panel array are on the end, so the massive 3-pin power LED plugin just hangs off by 1 hole and no other plugin is sacrificed.

Other Thoughts: I bought 2 of these things at the same time. I'll be making use of Newegg.Com's standard return policy for this product without even opening the other box.

2 out of 5 eggsNot a great case, keep looking

Pros: It is as advertised. Fairly sturdy, mostly easy to work with, drive hanger rests on strips of foam to cut down on noise.

Cons: Cooling is a major issue with this case. It has 1 120mm fan in the front, and two 80mm internal fans in the middle (on a rail which allows you to position them which is nice) but that's it and it's not enough to keep the components cool. I've got a Intel Core 2 Quad 2.66 (Q9400) running in its stock config, a 9800 GT video card (overkill but it was not in use), no 5.25" drives, one 7200 RPM HD and three 5400 RPM green/low power & heat drives. There's just no way those components alone with the stock config of the case should post a cooling problem, but they do. There's simply not enough airflow. My Q9400 can run well over 60°C and on at least one occasion has triggered thermal shutdown. I've added a pair of 80mm fans and that has helped some, but temps under 25% load still go over 60°C.

Manufacturer Response:

We at Athena Computer Power Corp. thank you for your feedback and will pass it along to our R&D team. Our suggestion would be to incorporate another 80mm fan to solve your cooling problem, and if you decide to do so we would be happy to send you another bracket for it. Please contact us at (626) 810-5008 or through our e-mail at and we may proceed from there. Thank you and have a great day!

2 out of 5 eggsBeautiful Case, great board fit. roomy? not so much

Pros: Was an excellent case as for being able to take it apart and put things in until you begin putting it back together.
On the plus side the screws for the case were in the right place and the motherboard anchored well. It was a Tyan Server board. Hence server case I think that was the other people's screw troubles came from regular boards in a server case.

Cons: The external bay hanger was too low and threatened to break my memory if I pushed it down, simply no room, I will have to mod the case to make it fit, as I do not believe the two middle fans will fit if I place the external drives into place. This case will take a lot of modding, had to get a dremel and will need to do a lot of cutting. Case won't hold all the drives it was made for. Just two or it will smash the board.

Other Thoughts: As long as you don't want too many drives and have a dremel and want to cut it up a bit I think you can make this case work...
