Well, I know the last 4 threads in this forum were by me, but I still would like some help x3

Well, a while ago my mum bought a cheap eMac from the college she works at, and well, with no decent computer to game with other than my Mum's laptop which overheats stupidly quick I would like to play some games on t3h eMac. I know about WINE and all this stuff, and I've looked at WINE, but I've got no idea how to download it let alone install it and get it running. Also, BootCamp etc. probably won't be an option unless my dad gives the all-clear. So, any suggestions or help would be cool.

Oh! Before I forget, the games I'm interested ATM are Counter Strike: Source, Half-life 2 and episodes, and Zombie Panic! Source (a HL2 mod)
