Acquired a recently bought slimline (s5 1214) from a guy at work because his son was unable to install the gaming card that he wanted. Needless to say for 200 bucks I'm pleased, I was using a 6 year old falling apart laptop.
When I opened her up to check things out, I noticed the psu female end on the mobo (Cupertino2) appeared standard size and from information I've read all slimlines have a miniatx connection not the standard white pin connector.
If this is true, I'll modify the case (or build one) and start modding the psu and gsu this weekend. Plan to also upgrade the cpu which is currently 2.8 dualcore.
