3 out of 5 eggs

Pros: OK chassis for the price and size. easy to install the system board in. if the stand offs and power cable were correct I would have had the server built in under a hour.

Cons: the power supply needs to have longer cables and not sure way 2 of the stand offs are half the height of the rest.... luckily I had some old stand offs the fit. also sure how you could fit all the drives it says with a system board installed.

4 out of 5 eggsGood Chassis; Looks Great

Pros: Looks Great
Arrived in Excellent Condition
Fits tons of drives

Cons: All the screws come tossed together in the same bag
Can be difficult to disassemble
Inconsistent packaging

Other Thoughts: I recently bought 4 of these to build rackmount computers for work. 2 of the posts where you mount the MOBO are short for some reason and come with standoffs. 2 of the 4 didn't have these standoffs and therefor my MOBO (the ASRock B75M R2.0) didn't ground properly causing quite a few issues. I spoke with customer service and the parts are on their way. Overall, I really like this chassis and will buy it again if the need arises.

1 out of 5 eggsNot Awesome

Pros: - Has room for desktop ATX PSU
- 3 x 5.25" Bays that face out
- 3 x 3.5" Internal bays
- Cases have a clear plastic wrap on them to prevent scratches which you can peel off (similar to that on the face of a new iPhone)

Cons: - Have to remove pretty much everything to install drives into the 3.5" bays
- Almost all screws and screw-holes are stripped by manufacturer
- PSU is inconsistant (bought 2 cases, one had 4 Molex, while the other PSU had 3 Molex -- both PSU's are Hercules Model # AP-MP53ATX40 and have the Athena Power brand )
- PSU's output 11.6 volts on the 12 volt connector which causes random shut-downs. Tested system configuration used only 222 watts, and had to buy new desktop PSU's to replace them.

Other Thoughts: - Buy lots of extra screws to replace all the stripped ones.
- Have a long neck magnetized screwdriver handy -- you will need it to install the 3.5" drives
- Throw the PSU in the trash when you get it as no motherboard uses 11.6 volts on the 12 volt.
- Drink lots of coffee and have patience.

Assembly of a basic system with 4 drives takes approximately 1 to 1.5 hours for experienced builders.

I recommend paying the extra few bucks for an iStarUSA or SuperMicro case with PSU as you will be forking over extra money for a PSU anyway).

*** Additional warning *** -- NewEgg RMA shows "Unfortunately, our records indicate that the manufacturer's labor warranty for this product has expired. Please contact the product manufacturer for additional service options." -- So this is a buy-at-own-risk item with no warranty.

Manufacturer Response:

Thank you so very much for your review. Please allow us to fully address your comments.

1) It is true that, due to the chassis design, it requires a few additional steps for assembly. An experienced system assembler will be able to fully install the system within 15-20 minutes.
2) ACPC does not provide stripped screws for any of its products.
3) There has been a change to the PSU cable configuration recently. There is definitely a difference between an AP-MPS3ATX40 from last year and now. Y-cables are available at
4) Your comment regarding PSU output is incorrect. It is indicated in this review that a 'high technical understanding' is present. However, Standard DC 12V Output parameters are between 11.4V~12.6V. The ACPC PSU is within Industry parameters as defined by Intel. Please contact our Customer Service for a link to the Intel ATX12V Power Supply Design Guide for your reference.
5) Although Newegg may indicate expiration of Manufacturer Warranty, we recommend any users to contact our Customer Service for direct Warranty support.

We do understand that some users may require additional assistance in the form of installation instructions, info as to which correct tool and tool size to use during assembly, and help to determine which PSU is correct for their specific system configuration. Should any users require info or assistance, we do highly recommend that the user contacts our Customer Service at or via landline at 626-810-5008. Thanks again!

1 out of 5 eggsNot a Professional Chassis

Pros: It's black.

Cons: Not designed for practical use. Four screws on the sides of cover, not a single one in the back. Drive bays are stacked and very difficult to install. Long, slender and magnetic screwdriver is needed to install. Power supply cable for MB is way too short! Not professional.

Manufacturer Response:

Thank you for your review. The RM-3UD370S40 is designed for general entry-level server tasks. We do understand that, at times, it may be a challenge for the user when attempting to select a server case that meets their specific requirements. Should any user encounter an issue, or have questions, please do not hesitate to contact ACPC Customer Service at 626-810-5008 or Thanks again!

5 out of 5 eggs

Pros: Awesome case- great construction, plenty of room to work and all steel. Put in a 3 to 4 backplane and its running 8 2tb hd's in a freenas box.

Cons: main power cable is a bit short from the power supply to the MB

Other Thoughts: Buy it!!!
