x56h34 : I did say PPC but I didn´t say it had to be a 240 Mhz/68060 :lol: I have got a 160 Mhz PPC/68040 in my tower and it doesn´t warm up much so heat is not a big issue. And if you leave the trapdoor open en put the A1200 on four little feet, only a few mm high, then it won´t cause much problems. :-)
