Chenbro Rackmount 4U Server Chassis RM41300-FS81

This case is built well. I was able to replace the fan module in the left front panel with another chenbro drive bay module I bought, with 2 SSDs in each 3.5 Bay and four HDDs in each 3x5.25 bay by using rosewill 5.25 and icydock 3.25 hot swap cages that fit perfect, then 4 HDDs internally and 2 more SSDs in the ODD bay. A total of 18 drives and then 2 m.2 drives on the motherboard. This little board is loaded with storage for truenas. Very satisfied.

this case was a great upgrade from my old one no more screaming fans of doom and my family thanks you. but in all honesty this case is great it looks good has plenty of room for my truenas server and isnt hard to work in

It's a great case, but they're shipping the RM41300-F1 instead of the RM41300-FS81 as listed. The F1 only has 7 riser slots and fits 3 double width GPUs. The FS81 has 8 riser slots and can fit 4 double width GPUs. You can see in some of the other views that some people are fitting 3 GPUs and others are fitting 4. I think it's a dice roll whether you'll get an FS81 or an F1 until this get sorted out.

attention to detail and quality is very high with this unit and apparently this brand. everything you "might" need is shipped with this unit. You will also notice that a lot of consideration was put into the design of this case. this currently houses the best machine in my computer room. my setup = 18 computers + 3 tablets +1 chromebook + 5 smart TVs 14 of my computers are servers = 8 web servers + 1 Storage area network (SAN - 16TB) + 1 untangle box (for firewall-dns-vpn-network monitoring, etc) + 1 media server + 3 spare servers (for testing and web server hot spare). this case currently houses my latest 16-core server build which runs ESXi for my VPS machines (12 virtual machines @ Centos 6.3 and Debian 7.3 ) and MySQL databases. Its runs cool fans are silent and vibration free (important for expensive 15000rpm SAS drives) And YES my "power bill" gives me nightmares and possibly PTSD!

This case is one of the few with upper fan mounts. Sadly, if you are running a full height video card (GTX 760), it is going to hit the stock fans. I was able to squeeze some 16mm thick ones up there. Lots of options for drive mounting. I ended up mounting another 120mm fan in where the 3x 5.25" bays are. The mount for the slim optical drive had the holes drilled in the wrong spot. I ended up just taping the thing in there with some gaffers tape. For my application, that is ok. In a production environment, that would be a no-no. The power LED should probably be licensed as some kind of weapon. It is one of those ridiculously bright blue LEDs. I tried to pop it out to replace is with something that cannot be seen from space. Sadly, I was unable to get the little sucker to come out. Ended up putting some window tint on the little cover window. Oddly enough, the disk access LED is really dim which is kind of annoying. The power and reset switchgear is kind of cheesy, but functional. Not a bad case overall. I have some that are worse. Certainly is solidly built, just has some annoying detail features that could use some tweaking.

No complaints. The layout worked perfectly for our rendering engines (we've purchased three of these cases). There is plenty of room for three very large graphics cards. The ventilation is good. Well built with solid, thick-gauge metal. Assembly is a little slow as entire case goes together with tiny machine screws, but finished build is clean and solid. We will purchase this case again for future builds.

This is an ideal machine if you are looking for a compact rack mounted case that can also be converted over to a tower. I put four amd 7970 cards in a single chassis with no cooling issues. Note I had to remove one of the two fans mounted on the inside of the top cover to allow for sufficient clearance to close the case.

Bought this case for a AI build for work. It works great. Only complaint I have is that it does have some sharp edges on the bottom of the drive bays. I did have to take out one of the top fans because the CPU cooler was too high. Ryzen 7960x, Gigabyte Areo D, 2x A6000 with NVLINK, 256GB DDR5 5600, 2x 4TB Samsung Evo 990 Pro in Raid 1.
