I'd personally advise to find a cheapo used metal case (used oldish ones will cost you far less than wood) and glue the wood on that. You can find oldish small server tower cases that offer all space you will ever need. They will be all f-ugly, but if you glue wood on them it's irrelevant.
Be sure to check the CPU that it has all the VM-oriented features (they improve performance), as some don't.
