HTPC currently lives behind the TV but the wife would like to push the TV unit back to make more space in the living room. We need more floor space as we have second little one on the way. The PC is made up of leftover components from my main PC and so it is an ATX mobo and PSU with an 8800GT for graphics, which copes surprisingly well for the odd spot of gaming. All housed in an Antec 900 which won't fit in the TV unit. The gap in the TV unit is 47 cm wide by 40 cm deep and 20 cm tall. My budget for a case is minimal, can probably stretch to £60. Everything I've found seems to be too deep to fit. Anyone got any ideas or am I trying to achieve the impossible and will I need to either spend more or replace the mobo with a micro atx one? if I have to replace the mobo will I need to reinstall windows? Thanks for your help guys and sorry if I've rambled on, I've slipped a disc in my back so I'm taking some really strong painkillers.
