When selecting the perfect chassis for your home theater PC (HTPC) it can be difficult to strike the right balance between looks and capability.  With multiple tuners increasingly becoming available in smaller and varied packages at more competitive prices, the form factor revolution in the client HTPC space made possible by no-compromise integrated processor graphics (IPG) systems is now a tangible reality for the primary HTPC as well.  Wesena has aggressively pushed into this space with chassis like the Micro-ATX/Mini-ITX compatible all-aluminum E5, which with its CE visage offers a near perfect look for the A/V stack.  There is some compromise because of the ultra-low-profile form factor but with two hard drive mounts, space for a slim optical drive and enough expansion to provide a viable enclosure for your main HTPC, it warrants a detailed look.
