## Overview

The SilverStone RM47-502-I is a versatile 4U rackmount chassis designed for professional IT environments, featuring interchangeable front/back I/O and mounts, support for SSI-EEB motherboards with 11 expansion slots including vertical GPU placement, and advanced cooling options with dual 160mm fans or a 280mm radiator. Its front-accessible design and modular components streamline maintenance and upgrades, making it ideal for dynamic, high-performance setups.

## Description

SilverStone's catalog for industrial rackmount chassis encompasses a wide array of form factors, allowing businesses and data centers to find the perfect fit for their specific needs. Whether the requirement is for a compact 1U chassis or a more expansive 4U or 5U design, SilverStone offers versatile solutions that balance functionality, performance, and space efficiency. One standout feature of SilverStone's industrial rackmount chassis is their innovative cooling solutions. Besides the ever-increasing enhancement of cooling performance, another hallmark feature that SilverStone rackmount chassis includes is flexibility. Many models offer modular designs, tool-less component access, and hot-swappable drive bays, simplifying maintenance and upgrades. To take flexibility one step further, SilverStone created two rackmount chassis designs that completely differs from the standard rackmount chassis in retail. The RM46-502I and RM47-502-I, two interchangeable 4U height form factor rackmount chassis designed with front-facing expansion slots instead of the typical position at the rear. This feature offers a specific set of advantages for users in scenarios where they constantly need convenience and ease of accessibility to the expansion cards, or if rear access may be restricted where maintenance and upgrades without requiring extensive disassembly. In the RM47-502-I, the case features a thoughtful design that allows not only the expansion slots to be interchanged, but the internal configuration can also be adjusted for the position of the PSU mount, and 5.25" drive cage; to better accommodate specific hardware requirement or user preferences. The handle bar position and rail installation direction can also be swapped from front to back, facilitating improved airflow and cooling efficiency, while contributing to the overall functionality and ease of use of rackmount cases. The RM47-502-I is equipped with 8 low-profile expansion slots plus 3 full height expansion slots in a vertical orientation. This vertical slots design allows the seamless installation of high-end cards such as RTX 4090 without the power connector intruding with the top panel. The RM46-502-I, on the other hand has 8 full height expansion slots in the standard horizontal orientation, but cannot comfortably fit larger cards that exceed standard room offered in 4U chassis. An expansion card retainer with vertical arms, has also been incorporated into the RM47-502-I, but differs significantly from the RM46-502-I as it needs to accommodate a vertically positioned graphics card. This variation prompted the design of an additional retainer bracket to ensure a proper secure placement of the vertical mounted card. In conclusion, the RM47-502-I, with its interchangeable expansion slots and adjustable internal configuration, introduces a level of customization previously unseen in standard rackmount designs. The thoughtful inclusion of front-facing expansion slots and adaptable features addresses accessibility challenges, making the versatility and adaptability it possesses particularly valuable in dynamic IT environments where hardware requirements constantly evolve over time.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great case for my home lab Siwss Army knife cloud server including a RTX-5090 GPU.
*by D***G on June 5, 2025*

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.

### ⭐⭐⭐⭐⭐ Great Silverstone quality, but here are a few things I ran into.
*by C***T on June 30, 2025*

Fantastic build quality like always from Silverstone. Just finished moving my Unraid server to this chassis. Here are a few notes for those who are doing the same. The included 80mm fans in the 2U portion of the chassis behind the backplanes are 15mm and not the standard 25mm. I bought some Noctua AF8s, but I had to mount them on the opposite side of the fan rail to have enough clearance. While that works, you then take 25mm of clearance away from the PSU area, which in my build was a real problem since my 1600W PSU was now too long to fit. I purchased a Corsair Shift 1200W PSU to relocate the cables to the large, open area normally used for a secondary PSU. Not a complicated problem to address, but I wasn't planning on having to buy a new PSU because of fans. I am happy that I stuck with the thicker Noctuas, though, because my HDDs are already running pretty warm in here. 45-48c are the hottest ones in my array (WD 10TB Red Plus 7200 rpm). The backplanes have fan headers and preset curves based on ambient temps. My ambient temp is 74F so it's not enough to speed the fans up enough to keep the drives below 45c which triggers the default Unraid alerts.This case does come with mounting rails, but they are not sliding, which is a shame for a case that is over $1,000 after tax.The dust filters are great, and the panels are nice and thick. I would have liked to see a flared edge on the end of the top and bottom panels towards the back to assist with sliding them on and off.Comes with all the accessories you need to slide and mount additional 5.25 bay devices (like for even more HDDs), which was a nice touch. The 4U top area has unobstructed airflow, and the three 120mm fans (not included) will blow straight across your motherboard and devices. It is a shame that this portion of the chassis wasn't 5U or 6U. Being limited to small air coolers that use 92mm fans means more heat, smaller fans, and more noise, and less overall performance. In my case, I had to move from a Noctua NH-U12 120mm tower cooler for my 2990WX Threadripper to an NH-U8 4U form factor cooler.Overall, I am extremely happy with my purchase. Thank you Silverstone for a great quality case.

### ⭐⭐⭐⭐ Inadequate Packaging - arrived damaged TWICE.
*by R***. on June 14, 2025*

I like the case, but it arrived damaged TWICE. The drive sleds do not seem to ship well- they can pop open during shipping and in my case this caused the black front plastic of the sled to snap off. I ordered another chassis and it too arrived with multiple sleds not not latched in place, and again, one of them was broken in the same way. That’s two $1100 server cases damaged on arrival back to back. Not a good sign! I think Silverstone should reconsider their packaging and find a way to make sure drive sleds don’t pop open during shipping.
