The latest in 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 250- to 400W. Four 40mm fans provide the ultimate cooling performance, while the filter cleaner reduces dust buildup to keep the interior clean.

  • newegg Saving space and doubling the server power With its reduced depth size, this 1U rackmount is perfect for saving space. The size of this rackmount chassis is viable for a mini-ITX motherboard. Additionally, server towers usually can only maintain one 1U rackmount at a time, but 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-1U100D 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 allows 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 250- to 400W. By incorporating a reliable case with an efficient 80PLUS certified power supply, this combination is truly ideal.
  • newegg Up to four ball bearing fans The 1U100DM comes with four 40mm front exhaust fans. They will keep your server cool by distributing a cool air flow onto your motherboard and the rackmount’s hard drive as well.
  • newegg Filter Cleaner This rackmount chassis 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 chassis. This filter reduces the cleanup time and any messes that may gather in the rackmount chassis; the filter is also washable.

3 out of 5 eggsNot a true 5.25" Bay

Pros: Seems well constructed. With good airflow for a fanless cpu

Cons: The 5.25" bay is not standard. it is slightly shorter than standard. Which means my fan controller would not fit. I think they should make you aware of that before you purchase so -2 eggs

Other Thoughts: This is a 1u case. So be prepared to customize your io shield. The shield is taller than the case. But all components fit.

4 out of 5 eggsUpdate to previous review for new revision

Pros: Since my previous review, I ordered another of these cases and it looks like Athena Power has made some good tweaks:

- The usb ports are now flush with the front, making it easier to plug in many devices.
- The hard drive mounting plate has holes drilled for 2.5" drives too!
- Better front port connectors.
- includes a blank generic ATX shield. You can cut it to custom fit your motherboard.
- replaced the plastic sheet under the motherboard with a thinner, removable one.

Cons: It can be difficult to near impossible to find compatible sliding rails for this case. But as for the case itself, the new revision basically fixed everything I previous had gripes about.

4 out of 5 eggsDecent and affordable for a low-cost rack mount

Pros: Lightweight and inexpensive. It's a perfect size if you just need to rack mount a server without many drives. Given how short it is, you can probably rack mount using only the front ears.

The case is compatible with Flex-ATX power supplies, of which Seasonic makes a nice 250W model.

It can hold two 3.5" drives (the drives are mounted sideways) onto the metal plate.

Has 4 case fans, so you have some redundancy.

Comes with a decent supply of screws and cable organization ties.

Cons: I paired this with a desktop motherboard and it fit almost perfectly, except some protruding screws in the CPU socket were bumping up against the sheet of plastic underneath the motherboard. The plastic is attached with a strong adhesive, and I ended up dremelling away a little bit to make it fit.

The four fans are simple two-pins, without RPM sensor or PWM capability. They attach onto a small board that has a molex connector for power. If you want to replace them, almost any 40mm fans should be compatible.

There's no easy way to get compatible IO shields, but I just run mine without the shield. Airflow pretty much needs to go out through the IO region anyway.

Depending on your power supply, it may be impossible to install a 3.5" hard drive on the inner side of the mounting plate, as it can interfere with the cables coming out of the power supply. Also, it would be nice if the mounting plate had holes drilled for 2.5" drives, not just 3.5". I ended up using a simple adapter bracket.

Recessed USB ports make it impossible to plug larger USB flash drives in the front without an extension.

Other Thoughts: The Dynatron K199 CPU cooler works well with this case. Just point the blower towards the back. If you are using a desktop motherboard, I would recommend low-profile memory as the ram slots would be positioned perpendicular to airflow.

The power button kind of looks like a toggle switch, but it works like a regular computer power button.
