The Level Twelve casemod from Jeffrey Stephenson is pretty decent looking if you like wood. The box is constructed from Teak and Birds Eye Maple and holds a 2TB hard drive, an optical drive and four front mounted USB ports.
Other specs of this mod include an i7-processor, 8GB of RAM, a 256GB Crucial C300 SSD and a Lenovo H320 case. Jeff makes computer cases look damn good. If we had computers in the 1950′s they would look like this.
