I Had a pretty normal Mini-ITX Case as my HTPC and frankly it bugged me just how "big" it actually was. I set out to "re"-make it as small as possible. One of the other constraints that I set: Use as close to nothing new as possible. That means I could only cobble this together out of "leftover parts" etc. I had an old 70 Watt DC to DC Power supply leftover from an old project, a leftover 2.5" Laptop Drive, an old Dell Laptop Power Brick (19 Volt output unfortunately), some misc fans, and other goodies. I felt I was in pretty good shape to begin this project. I looked at some old junk laying around as a new Donor.... Old DirecTV receivers, not bad. An Old Battery Backup UPS, some potential... AH! This old 7" Cube TV, Perfect!! The Motherboard is the Zotac Dual Core Atom/ION with Wifi. 1.6 GHz stock clock and it OC's to 2.0 GHz flawlessly. For HDD and Power LED's I cut up some acrylic and mounted Some Blue LED's into it (Sorry, I don't have a good pic of the HDD red LED in action). Here's the pics: Success!! It now occupies less than 1/4 the space as the old beast. The only thing I had to purchase was a Power Regulator that would drop the 19V laptop power supply down to 12v. Total cash out of pocket for this mod = $4.
