This is my first attempt at anything like this before. It has a 500gb hd, (overkill but it was a good price) AMD quad core CPU, 600watt power supply, 290 watt JVC home A/V receiver, (more overkill but I'm not one to turn down a freebie) a pair of Sony floor speakers I had laying around, another pair of freebie home theater speakers and a 15" ELO touchscreen from ebay. The cabinet itself is framed with 1x2s and will be enclosed with 1/4 MDF. For cooling I have a pair of 120mm blue LED fans to draw cool air in and will have another pair on top to blow how air out. As far as lighting goes I have a pair of sound activated Cold Cathodes.
