Rosewill 4U Server Chassis/Server Case/Rackmount Case, Metal Rack Mount Computer Case with 8 Bays & 4 Fans Pre-Installed (RSV-R4000)

I purchased one of these cases a few weeks ago. I built a Super Mac (Hackintosh) in it. I have an oddball 29U rack that it is in. I'm impressed with the weight and thickness of this beastie.. It's very sturdy. There is nothing cheap or flimsy about this case. It has tons of fans as well. Now let me note a few annoyances about this case. Changing or adding hard drives is a pain in the backside. The drives are in little slide out cages and that's pretty easy but putting the cables on or taking them off is a pain. Inside there is a large cross brace that has three 120mm fans. And the little plastic drive trays that slide in and out of the cages have to be removed from the back of the cages. You really have to remove that whole cross brace full of fans to be able to connect drive power and data cables. The handles of the drive trays are in the way of plugging the cables so it's just easier to remove the cross brace then put it back when done. In the face of each of the two drive cages is a 120mm fan. This helps keep the drives cool. One problem I encountered in my build is that I bought a Corsair Cooling Hydro-Series All-in-One High-Performance Liquid CPU Cooler CWCH60 . It has a little radiator just like a car has. It came with a 120mm fan that you connect to the mobo. There is a temperature sensor and a coolant pump in the cooling plate that connects to the mobo. You are ~supposed~ to mount the radiator/fan combo to the back of the case to exhaust hot air out of the back of the case. But this case do not have a 120mm exhaust vent on it, at all. It does have two 80mm fans on the back above the mobo connections plate. There was no way to mount the radiator to the back of the case, at all. What I had to do was rotate the cooling plate 180 degrees so the hose run towards the front of the case. Then I sandwiched the radiator between it's 120mm fan and the center 120mm fan that is on the cross brace. One fan pushes air through the radiator, the other fan pulls air through it. So that's a LOT of fan happening on the CPU cooler. The disadvantage is that it exhausts right in the middle of the case and blows across the mobo.. But that's really not a big deal, the air seems fairly cool and I have had no issues with overheating. So that said, the case is pretty darn nice overall. I like it enough that I've ordered a second case for an NAS (SMB/CIFS/AFP) & LAMP server I'm building. I like that it has not only room for 8 drives via the cages but if you must, there's room for more drives by adding some custom DIY mounts inside. There's no reason why one couldn't mount 12 drives in one of these cases. I could see myself doing that to be honest. Next month I will be buying a third case for another system that is an HTPC. It has an S2 satellite tuner in it and is connected to a bunch of very large C-band dishes. Currently that machine is running in what is probably a 10 year old PC type tower. It's ugly and has cooling issues. Another one of these cases will solve that problem and allow me to put more drives in it, something I've been needing to do for quite some time. Surprisingly enough, these things are not loud at all. With 8 fans in it one would think it would be deafening. It's not. I sit right next to it, less than 18" away from my left ear for 16 hours a day and it doesn't bother me at all. But when you lower the face cover to access the optical drives, it does get a little loud. Also, if your rack has a door, you can't close the door because of the handle protruding from the front. You can remove the handles but then you loose the face because it's hinged via the handles. I don't have a door on my rack so that didn't bother me at all, I left the handles as is. They need to redesign the back of the case to allow for a 120mm fan for those of us that use liquid coolers. Not a show stopper though, I worked around it. The dust filter could be a little better, I see it drawing dust through the filter and collecting on the face drive cage grills. It keeps out large dust and pet hair but not ultra fine dust. I'm going to end up putting a HEPA filter in the front. (cut up a HEPA vacuum cleaner bag) The drive trays could be redesigned to be a little sturdier and perhaps have handles that fold up or down so you can get to the drive power/data connections easier. The face could be redesigned to hinge differently so people can remove the handles if they need for doored cases. The complaints I have with this case are all trivial and easy enough to work around in most cases. Maybe on their next revision they could tweak things up a little. Overall, I love this case, it's the very thing I've needed for years. I bought a second one and will buy a third one in less than a month. I very well may buy a fourth one to keep as a spare for any future machines I may build. And I probably will. Come to think of it, I will probably order a 5th case.. Why not? I totally recommend this case to anyone that wants a nice, very sturdy rack mount case. It's worth every penny. Just be aware there are some minor, trivial issues that may or may not be a show stopper for you. Also, go to Rosewill and look at their photos, they have several photos from different angles that show much better detail that Amazon shows. They also have a PDF of the manual/instructions you can download if you want to research it before you buy it. I don't see how anyone could really complain about this case, I certainly can't. I rate this case at a full tilt FIVE STARS... I would give it six stars if they would send me a dozen of these cases for free.. :D Update: I purchased a third case before the weekend was over, they weren't going to ship until Monday so I went ahead and ordered one more. So I have one in use now and two new ones ordered. I got to thinking that if I snooze, I might lose. I would have myself forever if they discontinued these cases and I couldn't get that third case next month. Now I will be able to migrate all my machines into one rack and everything will look nice and have proper cooling not to mention, room for LOTS of drives. Three of these cases solve a lot of problems I've been bothered by for years. If these cases are still available next month I'm going to purchase two more for a total of five. These things are a bargain and a steal. One word. Awesomesauce! :)

This case is by no means the most refined or sturdy case I have ever seen, but it is also very affordable for the quality you do get. I purchased the 4U (8 bays + 4 fans) configuration. I installed 2 hot swap bays in the front without issue. The 5.25" drive mounting is a little weird (there are stamped metal pieces with nubs that go into the drive holes. Those feed into the case in channels with a little metal retention clip holding them in. These work fine, just not as nice as some of the more expensive tool-less cases. Also removing them on the bottom side of the case sucks, so don't slot something in unless you really don't want to remove it. The internal HDD bays have some nicer pull out plastic pieces that you wrap around the 3.5" drives, with tool-less nubs in the drives that slide into the cages (being held in with those metal pieces above). The case has a few sharp edges which are more common on less expensive cases like this. There is plenty of room for my build which is a full ATX motherboard with a pretty long 1500w PSU. The stability of the case seems fine. I removed the horizontal brace to accommodate my AIO rad and the case still feels sturdy enough without it. I have the case installed in my rack without rails, just using the ears and even though it is a heavy install it held it fine (just have another person there to hold the back up while you put the screws in). The door on the front is removable with a Phillips head screwdriver, so if you need physical security you should note that. The buttons and IO on the front feel fine, the only thing I would say they could change to make the case better would be the mechanisms that hold in the 5.25" blank covers. They fit by retention only, and can be a real PITA to get back in if you take them out, or knock them out by accident. They also will move if you bump them. I personally would have liked them to be screwed in, even if it ruins the tool-less on everything design but that is just me. They are kind of ugly too, but it's a server chassis after all so no biggie. Overall I would by this case again. If it is for an AV rack make sure your rack is deep enough to accommodate it (I have an AV rack in my living room data closet and it was just barely deep enough and I had to move some wiring just so it would clear.)

Rosewill is known for making cheap, yet good cases. This case is a good example of that. It's perfect for a Micro-ATX motherboard and fits a regular ATX power supply. It has a fan hold on top of the case to allow your PSU access to fresh air. Inside the case is tight, but everything does fit. The case is strong, showing no signs of flex while being mounted to my server rack. It has room for 4 hard drives, which may allow you to use it for NAS, depending on your needs.

If you get this on sale, this is a FANTASTIC case, except the fans. They are junk. Pure junk. I will be replacing them eventually. This case is heavy. Easy wire management, excuse my horrible picture of my horrible wire management. I was in a rush. You will have all the room you need to work, the centre fan stack comes out with the removal of a screw allowing you to run wires as you wish. AGAIN, use caution on the fans, nearly shorted out my MOBO when I turned it on, because one of the connections wasn't properly seated into the white plastic housing. As in, one wire was loose and free for the power. This could have been a very expensive disaster. For the price, you wonder where corners were cut. It was the wiring and fans. Get rid of them. If you buy, ENSURE YOU CHECK all the plastic housing for the fans power. Again, nearly lost my MOBO because of a short and spark when I turned it on. The HDD cages work excellent. My old tower case 12 HDD's were running between 35-45 degrees. This has dropped down to between 25-38 degrees, give or take how large the HDD is. 8TB's are running hotter than 3TB for example. Airflow is good in those cages, and will be better after I change fans. I don't rack mount, so I can't speak to it. Mine is placed in the TV cabinet, with about 8 inches of clearance above.

Its not a perfect one. But not a bad one either. Pros: - No bends or dents on metal as it comes from usa. (Packing was 5 star) - Perfect suite for Micro ATX or smaller if HDD metal supports are used - A normal PSU would fit in perfectly - Large number of 3 types screws are included. Good quality screws. - Stand off threads are built-in on chassis Cons: - Setup was not very easy in the end when putting all screws back. But with some adjustment of screws here and there, it can work ok - Initial 1 fan was not working. But when I loosened a screw on chassis which was under that fan, it was working. - The fan’s power connectors are cheap quality that the pins came out - Mounting bolts and screws are not included

I purchased this for a plex server because I needed the 6+ harddrive bays for lots of storage. Not many upright options on the market at this price so I decided to do a rack mount. Very happy. It’s not a fancy, RGB case but it’s super functional. Not extremely heavy, I actually have it mounted horizontally to the wall. Comes with 2 120mm fans in the harddrive bays, one 80mm rear fan. Fans are not the best quality but they work for my purpose. Has a key lock which is convenient. Screws are terrible, I replaced most of them with higher quality screws after stripping many of the stock ones during install. Big enough for a full sized graphics card (I have a 1080TI) and lots of PCI bays. Since most of us don’t use optical you can easily buy or 3d print mounts to fill the two disc drive bays with more drives, I have 9 hard drives installed. If you want something that works this is not a bad case. Be gentle with the screws and you’ll really enjoy this product.

Overall a great experience and a great product. Very cost effective for a music and video editing rig, rack mounted. Nice and quiet, fits perfectly, lots of room for gear. Some of the fasteners as perhaps a little bit old school but I enjoyed the build and the system is running great! Recommended
