flexibility, and durability, the RM41-506 is a great choice for
professionals or data center engineers looking to build a server.
Review: Great case for my home lab Siwss Army knife cloud server
including a RTX-5090 GPU. - Great upgrade 4U case for my home lab
cloud server. I needed more room to add a RTX-5090 to this rig,
and didn't want to go all the way to a 5U case. To be clear,
there is only one 5090 card brand (Zotac) that will fit this 4U
case with enough room on top to comfortably fit the 600W
connector & wiring. If using another brand, I would probably go
with a 5u case. I installed the Zotac Solid OC specifically in
this build. Other Zotac models will likely fit as well. The
SOLIDs 137mm height is a perfect fit for this case (which
specifies a154mm max height). The case came with a number of
front GPU support brackets. I used one, and it makes for a very
solid mount. The 5090s aluminum frame holes at the front of the
card lined up perfectly with the holes in the provided bracket.
With the card secured with three screws in the back, and the case
bracket in the front, I am confident the card will not come loose
when removing/installing this case in my rack. As far as cooling,
the case will fit one Noctua NF-A14x25r G2 PWM (140mm) and two
NF-A12x25 PWM (120mm) in the front panel. It is tight, but can be
done. Use the adjustable slots instead of fixed holes to slide
the two 120mm fans far to the left and right sides of the case to
leave room for the 140mm in the middle. I loaded this case up
with a total of 8 fans (added a custom slot bracket with (2) 40mm
fans for a total of 7 case fans and a Noctua NH-D12L CPU cooler
w/fan). This configuration provides fantastic airflow and dropped
the CPU temp by a solid 20C over the previous 2U case which was
cooling challenged even with a Ghost S1 CPU cooler and (4) 80mm
case fans.. Overall well made case. Even with a 10G NIC card and
the RTX 5090 installed, there is still room to access at least 2
of the SATA 2.5" mounting plates comfortably (no wires/cards in
the way). I now plan on adding a couple of large SATA drives in
raid mirror as a home network file server and for backups, making
this machine even more of a Swiss army knife of a server. This
combination of fans is almost completely silent, even with a
moderate load. With the fans at 100% it is only noticeable if you
are in the same room, but I doubt you would hear it in the next
room. Overall very happy with this case. One negative ,but not
enough to remove a star, the manufacturer does not sell a set of
sliding rails that fits this case in short racks (slightly less
than 22" deep). This case uses screwless rail studs to connect
the rails, and there is no option for screw on rails. The only
rails designed for this case are too long for my rack. I ended up
using the Cyber Power 4POSTRAIL, which worked, but is VERY tight
when sliding in the heavy duty rack ears on this case. Installer
trick, don't lock down the rail mounting screws (just hand snug
them). After you slide the case in fully (might take some
wiggling), lock the back screws and the bottom two screws in
front. This will lock the rails in place with perfect
spacing/alignment, then you can pull the case out and lock down
the top two front screws.
Review: Plenty of room for activities! - This is a great rack
mounted case. You can run single or redundant power supplies, It
fit my ATX motherboard and RTX card with plenty of room to spare.
I have a 360mm AIO cooling system for my CPU and this case
handles it with ease. Airflow is consistent and has a well
defined path - front to back. Noise levels vary on system load
and environmental temps. Plenty of USB ports in front, though I
would have liked to see 2 CD/DVD drive bays. Mounts EASILY into a
standard rack. Needs 4 screws. Can be mounted to rails to slide
out if you want to go that far, however the rails are not
included with the case and must be purchased on their own. If you
wanted to put the case on it's side and not mount it in a rack,
you can do that also. I can see myself re-using this chassis for
multiple system builds.
