My 040 did just fine in a desktop A1200. I've overclocked it to 40Mhz, and as a precaution have removed the fan, added a heatsink and stuck the fan back on top. The 040 card is mounted in a tower case so heat isn't too much of an issue - however I do have a nice 5 Volt fan I was planning on plumbing in just in case :-D
