I just replaced my desktop, and have my old desktop sitting in the corner completely unused. It is a Gateway DX pre built, I was considering gutting it and using some of the parts to build a htpc. I was hoping I could use the motherboard, processor, and ram. It has an acer ipimb-ar rev 1.02 motherboard, and a I5 3330 cpu, 8 gigs of DDR3 ram. If I buy a slim micro atx case, would this work, I have even considered putting a budget GPU in it for 4k playback of content.
