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.. :DUpdate: 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.)
