Silverstone RM42-502 4U rackmount Server Chassis with Liquid Cooling Compatibility, SST-RM42-502

This is a great case, it does not require an SFX power supply and it supports a full size ATX motherboard. That's the punchline, folks. If you want a 2U case you're either dealing with SFX power supplies or ITX / mATX boards. Not with this case. You can use nearly any PSU you want. And considering you could never use 1300w of components in this case, this is a non-issue. 850W Seasonic? Easy. They put the power supply in the front of the case, which yeah, is arguably weird. But if it was in the rear you could not have an ATX board. Or they could have tried to smush an SFX in there or used some proprietary PSU but that would be awful. This is the best of both worlds. And yes this does mean there is an auxiliary power cable going from the rear to the front, and it requires a somewhat sharp bend to plug into the PSU but when you properly disassemble the case and carefully bend the cable its no big deal at all. And yeah, you gotta buy a 2U cooler. Its a 2U case afterall... While there are some low profile coolers that would work, you don't really want the airflow going that direction in a 2U case. I even created a custom magnetic dust filter for the front which makes it even better. Great case.

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.

At the time of this review, I've had this rackmount case for a few months, and it's currently out of stock and I hope that changes. This was the best rackmount chassis I found for my project and it works beautifully. The unit was designed and built well, quality materials were used, and overall a very user friendly case. I am using it to house leftover pc parts running ubuntu for fun tests, and this chassis can easily handle most builts within spec. If this product becomes available again, please buy it. It's a great buy. The only request I would have is to have a 3U and a 4U option available in the same style with front fans. They might exist but I don't see them here on Amazon. Keep up the great work Silverstone!

This is a modern industrial/workstation/gamer/dvr/daw 4U case. You will not be disappointed. I bought two. It's a perfect blend of old school and new school design. For example, it has two 5.25 drive bays and supports 280 mm coolers (and unofficially 360 mm if removing the 5.25 drive bays). Attached to the 5.25 drive bays, you can mount two 2.5 inch drives. It has up to three com port knock outs. I always appreciate at least one. You can easily route/modify this particular area to attach other peripheral connectors, in my case, the daughter card to the RME RayDAT card. You can use a dremel for this. Make sure you vacuum the case very well to remove any metal shavings. My next modification will be to route the full area above the pcie slots to hang up to two more daughter cards. The case is on the lighter-weight side, but sturdy, BTW. One other note: it appears the entire back panel can be removed if you unscrew it. Though I didn't try this.

You already know what you are looking at, so I will get straight to the problems. 1. The interior power cord extension (plugs into your ATX PSU and extends the receptacle to the back) is poor quality. It has no no safety markings (UL/ETL) and unbelievably, would not fit in my power supply (Seasonic Prime GX 1300W). The plug tolerances on the cheap *hardwired* (not replaceable) extension cord inside the case are subpar. This means it will fit in some PSUs and others will require you to sand down the plug. 2. The bend on that cheap internal extension makes me uncomfortable. You cannot relieve the strain due to how the PSU mounts. 3. Rails should be included at this price. They charge an additional $70 for rails and they are often out of stock. 4. If your mobo uses angled connectors for USB3 or SATA, you are going to have a tough time with the clearance between the side of the board and the mid frame. 5. You should also consider the need for a 2U CPU cooler, also sold separately for $40. All in all, I would research more options when it comes time to buy another.

Overall it's very underwhelming for the price. The vertical oriented hardware is cheap feeling. I thought it might be a feature I'd use but the hardware is not confidence instilling and once it's rack mounted you'll probably never use it. Not a lot of space for SSDs unless you convert bays. Its a pretty solid unit but there are comparable cases for half the price.

It's an awesome case. Very sturdy and roomy. I was worried about clearance, but everything fit with literally no room to spare. Here's my specs for reference: Motherboard: ASUS TUF GAMING B550M-PLUS WiFi II CPU: AMD 5900X CPU Cooler: Thermalright PS120SE GPU: ASUS ProArt 4070 Ti Super Power: Seasonic Focus V3 GX-850 The only con is the noisy stock fans. I will be replacing them.

I am using this for a game server that I have mounted in a server rack. It is running an Intel i7-11700K and an Asus motherboard. The cooler is an EK-AIO cooler which I chose because based on the specs it seemed to have the longest hoses to the pump and also the top hose looked lower than other options when mounted sideways as is required in this case. There is plenty of room in the case as it is basically a tower case with rack rails attached to it. It fits a standard desktop/tower PSU. There is no space behind the motherboard so any cable management has to be done in the area above the motherboard and between the motherboard and media bais/AIO mount. Since this is a server it is not much of an issue. The front is vented so if you have some RGB you could see it partially but I opted for a non RGB AIO as this is in the basement anyway. One big drawback is the power button and USB panel in the front takes up so much room that the drive bays are vertical when the case is rack mounted. There is plenty of space to mount them out of the way and I wish Silverstone had done this so that I could mount drives horizontally instead of vertically.

I love how much space is inside of this case. They really made the most of the 4U height, and while right now my system is pretty basic, I know I could use this case as my system grows and expands over the years. Only problem I've had with it so far is that rails are nearly impossible to find. And especially for shorter depth racks (mine is roughly 18"). I'm using a 2U inverted shelf as a stop gap until I can find something more suitable. Any way, going to be keeping this one a long time!

2U cases are designed for a limited foot print and you should only buy this case understanding that: 1. You will be limited to a CPU cooler height of <70mm. 2. There are limits to the size of Power Supply you can use. Most rack cases require you to buy a special form factor of PSU. This one can fit a standard ATX PSU under 160mm in length, so an 850W will fit no problem. 3. No rack case comes with rails - it's always something you need to buy extra, with much more expensive cases (not saying this is good, but it is the reality). 4. Only low profile expansion cards are supported. The user who left this review would have been better off buying a 4U case to convert their desktop over to rack mount. That being said, what this case does, it's very good at. You can fit an ATX mobo/PSU inside, which is hard to find for a home lab. It's got excellent airflow (front to back) for cooling. Convertable 5.25" bays for more drive storage. It's great bang for your buck. Comparable cases from Supermicro are 2x-3x the price.

I'd feel safer locking my valuables in this thing compared to an Amazon basics safe.
