As the latest addition to Athena Power’s mini-server product line, the RM-1U100DM rackmount chassis is designed for small businesses, and for mobility for all IT system integrators. This ultra-compact chassis offers one 5.25" open bay to support up to four hot swappable 2.5” HDDs. You can also daisy chain multiple chassis for expanded usage. The high-efficiency chassis is compatible with a Flex ATX Power Supply from 250W to 400W. Four 40mm fans provide the ultimate cooling performance, while the filter cleaner reduces dust buildup to keep a clean interior.

  • newegg Compact chassis with daisy chain capabilities With its reduced depth, this 1U rackmount is perfect for saving space. The size of this rackmount chassis is viable for a mini-ITX motherboard. Additionally, with the 1U100D’s daisy chain capabilities, one server tower slide can hold up to two mini ITX rackmounts at the same time.
  • newegg Hot SWAP Capabilities The RM-1U100DM comes with a 5.25” open bay and is compatible with the BP-425SAS and BP-425SAC, allowing support for up to four 2.5” HDDs that are hot swappable. This provides server administrators and system engineers extra mobility, so they can be flexible with their needs.
  • newegg Built-in FLEX ATX PSU Athena Computer Power also offers combinations of this ITX rackmount and a Flex ATX Power Supply ranging from 250W to 400W. The RM-1U100DM308 is ideal for demanding server applications by incorporating an efficient 80PLUS certified 300W power supply
  • newegg Up to four ball bearing fans The 1U100DM comes with four 40mm front exhaust fans. They will keep your server cool by distributing cool air flow onto your motherboard and the rackmount’s hard drive as well.
  • 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.

3 out of 5 eggsThings of Note - Update

Pros: So I'm updating my review from the other day... After only a few days the included power supply has failed. That's very disturbing. Rather than waste my time returning the whole case (and ripping out the PC that I built inside it), and dealing with the hassle, I just purchased a new power supply from Newegg - made by FSP. I'm far more impressed with their power supply build quality and performance that this hunk of junk from Athena. The case, however (if you ignore the power supply) is a great case, and I still love it.

Cons: n/a

Manufacturer Response:

We at Athena Power apologize for the inconvenience, our RMA process does not require you to return the whole case to RMA a dead power supply. You can simply just send the power supply to us for an RMA. If you would like to conduct a RMA for the power supply. Please feel free to contact us at or call us at (626) 810-5008.

4 out of 5 eggsThings of note...

Pros: Nice little 1U case, very attractive, side rackmount handles are removeable, full black chassis and front bezel (if you pull the handles off you can use it as a desktop case or for a HTPC case), comes with a solid 300 watt power supply. Plenty of room.

Cons: The back plate will not accept a standard motherboard I/O shield. Personally, I don't care and I'll just run without the shield, but if this bothers you, then you can either a) order one from the case manufacturer separately, or b) get a cutoff wheel or dremel tool and cut about 1/8th of an inch off the top and bottom of your motherboard's I/O shield. Also, the 4 included fans struggle to say the least. Air flow is poor. I suggest upgrading to 4 of these fans - sold by Newegg - -- it'll really make a huge difference in cooling performance. Lastly - be sure you get a GOOD 1U processor heatsink / fan. For an AMD FM1/FM2/AM2/AM3/AM2+/AM3+ then this one will do nicely --
