In Win IW-R300 3U Server Chasis Review



The In Win IW-R300 server chassis has a lot of great qualities that set it up as one of the best for the price. However, for the price, I feel that the IW-R300 should have come with the two 60mm exhaust fans, as they make a big difference in keeping the components cool - the one 80mm intake fan that was included is just not enough to keep the hardware under suitable temperatures. Also, since this is a rack-mountable case and because of the size and weight, I feel the rails should have also been included in the package. With the average price of the case being around $250, this could have been an easy way to overlook the cooling issue and make this the best server case I have used. It is a pain to unscrew and lug the case out of the rack every time you need to perform maintenance or make a hardware adjustment. I did this several times over the testing period and finally gave up screwing it in and just rested it above a server I already had on rails.

Now, with that being said, this has to be one of the easiest and best server cases that I have used. I have built many servers for my studies and personal business, both rack-mounted and tower-based. With the price and time it takes to obtain 1U or 2U hardware, it makes it more feasible to use a 3U or larger chassis for my builds. This particular case made building a server possible via easily to obtain, off-the-shelf parts, making the unit not only cost effective to build, but also easier and cheaper to maintain. The space for five hard drives means that you have plenty of storage options and, if you use a slim optical drive, then you can even populate the empty 5.25" bays with a drive cage for more space. The included 2U single power supply provided enough juice for what I needed, but if you need more than the four SATA power plugs, make sure you have adapters for the Molex plugs to convert them. If you’re looking to convert a system to a rack or need a solid rack chassis for a server or NAS build, then I highly recommend the In Win IW-R300 server chassis. This unit has the best qualities in a rack mounted case, by far.
