IN-WIN IW-RF100-S315 1U Short Depth Rackmount Server Chassis, ATX 315W Gold PSU

IN-WIN did a good job thinking this case out. Really like it's features.Build quick specs: 9900k (95w TDP), 32GB ram, optane 32gb drive, ATX motherboard, Intel x710 dual 10g spf+ card.1. You can swap the power supply and front USB/Status LEDS/Buttons cluster so that if you reverse mount it you have your buttons, leds and usb with the IO like I did in the pictures. Very nice that they built in reverse mounting for the PSU, takes about 5 mins to do and is just 8 screws and done. As we are using this as a firewall / router machine on a 10g network, It's nice to have the IO forward facing and the power rear facing. Was really glad to find this.2. IF YOU NEED A RISER and can't find one, I had to order 4 to find 1 that works. This 8X 90 degree riser ( WLGQ PCI-E 8X - https://amzn.to/3YeM8q9 ) did in fact work and is the exact height you'll need to use the full height slot. ( I have not found a 16x, but my x710 is only an 8x card so it works )3. IF YOU NEED A 8th/9th GEN CPU COOLER, ( Dynatron K199 - https://amzn.to/4dz4Tcb ) this is a much better option for cpu cooler than the flat fan on top ones. This one is solid copper with a real server blower fan, and you can mount it in any direction to blow the hot air which ever way you need (handy in a cpu case that you can reverse) It fits perfectly on 1151 socket cpu and is up to a 125 watt TDP cpu. But I believe it could actually handle more than that. The K199 cpu cooler is nice and well built. ( Can google the specs on the K199 )4. Most Intel ATX motherboards have a cpu socket back plate. The 3 screws on that stick out ever so slightly. Get some nylon washers and put under each mounting screw if you don't like the motherboard bent a hair. I went without as motherboards can have some flex to them, but if you want no flex get a pack of like 5mm i'd say nylon washers to keep that from happening. Just a 1u issue but easily remedied.5. You will need ram that does NOT have heat sinks on them. Maybe the corsair type that is thin might work? Dunno it'll be tight, i don't have any to test, but I did have ripjaws and they do NOT fit. I ended up going with the best i could find, ( TEAMGROUP Elite DDR4 32GB Kit (2 x 16GB) 3200MHz - https://amzn.to/4eNKeSC ) They have a 64GB kit too (64GB - https://amzn.to/3Byy9CC ) these fit perfectly and are at least a performance 3200mhz ram kit for the price.Happy Building!

Decent short-depth rack. One odd thing is the power supply doesn't have a 4 pin CPU power cable, which wasn't a problem in my low-power build. The included fans scream at you, so not suitable for being in the same room, and I replaced them with lower flow but much quieter Noctua fans. This may or may not be an option for your build, so check your temps! You will need some kind of riser or PCIe extender to make use of the card slot, which sits parallel to the motherboard.

The design is well thought out. Plenty of ventilations, allows for 1x 3.5 inch and 2x 2.5 inch drives, along with a full sized ATX motherboard.Keep in mind the limitations of 1U. The case is not very tall, so if you plan to use this in your home (like I did), with consumer hardware (same here), then beware of the following:I am using an older LGA 1155 board, which has DDR3 RAM that have heat sinks. Something like G.Skill Ripsaw will not clear the case. I had to replace the stock cooler with a 23mm CPU cooler, as the stock was way too high. The fans that come with the case are little wind tunnels and extremely loud (sounds like a drone flying in your house). Worst was the soundcard output on the MB. It was 2-3mm too tall, so it had to go. If you have any I/O ports on the back that are taller than say the USB+Ethernet stack, it may be too tall (I didn't measure, my fault). This also means the I/O shield wont fit.Aside from the $60 in fan upgrades, the case works well. Fits in with the rest of my networking gear and I plan to purchase another.

Screws are cheap trash!!!!!! Trying to remove the wimpy PSU thats included to upgrade to a better is next to IMPOSSIBLE. Half of the screws stripped with just a regular screwdriver that I have used for many years. CHEAP!!!

No problems overall with the case. I was very surprised to find out the PC Case maker In-Win also makes Rack chassis. Ample room for a mini ITX or m-ATX motherboard. I do have an issue with the manual online not being too specific on the placement of some screws and needing to figure out how to swap some parts around myself. The IO Shield is a non-standard size, probably due to the size restrictions. I cut one one from cardboard to at least keep the airflow inside. I also had to remove the 3.5 inch drive bay since I swapped the front IO to the "back" and same with the PSU to use the motherboard IO and PCI slot in the front.Double check everything. Sizing does matter here, and some boards will flex a little due to having a backplate or electronics on the underside of the board. I used a CWWK motherboard with a silverstone 25mm cooler. The noctua 37mm low profile cooler does not fit.The PCI-E slot also requires a right angle adapter to fit properly. A left angle adapter does not fit.The main reason to chose this one over the other shorter, and smaller PSU brother is the PCI-E slot and reversible parts. The PSU and Front IO can be swapped if you wish to have the Mobo IO and PCI slot to be front accessible.Overall, very happy with this chassis, other than the light manual, very modifiable. I plan to add dust filters on each side to prevent dust being stuck everywhere.
