OCC has published a review on the In Win IW-R300 3U Server Chasis

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.
