## Overview

The SilverStone 2U rackmount server chassis SST-RM23-502-MINI is engineered for professional-grade server builds, supporting M-ATX and ITX motherboards, dual 5.25" drive bays, and multiple HDD/SSD configurations. It offers flexible power supply options including single and redundant 2U PSUs, dual USB 3.0 ports for high-speed connectivity, and optimized cooling with fan brackets. Designed to fit standard 2U rack spaces, it balances compact form with expansive internal capacity, making it ideal for demanding home labs, multimedia servers, and enterprise environments.

## Description

The Ml09 is an evolution and variation of the premium Mini-ITX HTPC case, The Milo Ml06. With external Dimension unchanged at 7 liters, the Ml09 rearranged internal layout provides a crucial second expansion slot for support of more powerful low-profile discrete graphics card or expansion card that are two slots wide. For users that wish to build with a more robust GPU or tuner card in console/dvr-like form factor to game or for multimedia content recording, the Ml09 is a great starting point

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.

### ⭐⭐⭐⭐ Great case for gaming/editing machine to use in rack. Lots of room. Easy fit with AIO water cooling.
*by S***A on September 10, 2022*

I've had this in use for a few months now. If you don't have an extreme setup or anything, this will do nicely. My older editing rig that I wanted to test this case out with is listed below. I wasn't sure how this was going to work -- would the airflow be good? Would everything fit? How noisy would a 'basic' server case be (clanking, rattling, etc)? So far, I'm very pleasantly surprised at how simple this change over was. Reading the comments, it made it seem like it would be more trial and error, which I didn't experience anything other than a straight forward drop in. With the rack in my closet, I never realized how quiet my computer room could have been many years prior to this. Wish I did this a long time ago. Way more expensive than going a simple desktop case but well worth it. When editing or gaming in this case, my temps are not any worse than with my high flow desktop cube case I had (Corsair 540). I typically stay ~55-58c during video rendering and during gaming the gpu is ~60c with a mild fan curve. Even in the closet, the stock fan curve was louder than I wanted but kept temps down in the low 50's. So I figured the trade-off of >10c for much quieter sound was worth it. So if you're worried about this case not having all the fans you've become accustomed to with gaming cases, don't fret. A good AIO cooler (the Arctic II is excellent and fits great in this case!) and two Noctua 80mm fans on the rear keep the flow decent with minimal sound. Components i7 6850k (oc'd to 4ghz) x99 Titanium ATX mobo R9 Fury 4 x SSD's Arctic II 240 Cooler I ended up not using the gpu bracket or hdd cage. I just stuffed my 4 ssd's in the area for 5.25 devices since I'll never use that for anything. Cable management is easy but not as much of a requirement for something that will be tucked away. Sure, you still want it clean and easy to work on as well as keeping the restriction of airflow down, with that in mind, it's nothing to get the cables out of the way. The case is solid and sturdy. When put in the rack with the lid, no rattles from the case whatsoever. With the front lockable door open or closed, it made no difference in my temps, so I just keep it closed. Love the usb-c port on the front! Mild cons: It's pricey. Can't find good quality sliding rails to work with it. Will be moving my other 2 computers into these cases over time.
