I started this build to replace a much larger ( Cougar Spike ) pc I was using a HTPC. I wanted something cheap, low power, low heat but that could stream and play 1080p. I had a few parts already which helped, but if you didn't already have them you could still buy them and be right at $300. The IN WIn BP655.FH300, was about the cheapest, smallest, best looking case with a PSU already in it. This is the usb 3 model which comes with a 300 watt psu. The motherboard I got with a combo deal, the MSI AM1l, nothing special but the combo with the AMD 5350 was $50. The motherboard has back usb 3, but no usb 3 header. I bought a usb 2 to usb 3 cable for $3, solved the problem of not being able to hook up the front usb 2 ports. The hard drive, ram dvd drive were pulled from a different pc to upgrade it last year. Nothing fancy, a small Samsung 128gb SSD and two 4gb Kingston 1600mhz sticks of ram, HP dvd drive. I didn't end up using the fan in the pictures, turns out the fan is not loud and moves enough air. I used Windows 10 Home, well because its about the cheapest version of current Windows you can get and it works fine. After running some tests and benchmarks, idle is a ridiculous 19c and max was 26c in a in a 24c room. While using it for normal tasks and web surfing it does fine and seems zippy. Video playback with Blue-ray rips over the network from my server play perfect with no hiccups. Also 1080p YouTube videos play excellent. I wouldn't use this to do any content creation or gaming, but for what I wanted it for, its perfect. I did get a very small overclock off of the cpu in bios of the MSI board, 2.05 to 2.1, not much but I'll take it. I didn't really notice a big difference, only in benchmarks, which got a small bump. Overall its a good, cheap little HTPC. I threw in some pictures of my other cases to help show the size of the IN Win BP655. The larger case is a Cougar Spike and mAtx slim is a Rosewell R379-m.
