Neat thread, I came upon one a HP T5740 that was getting tossed and decided to do something similar. I'm going to use it as a home automation server, so didn't need a ton of space, but the 2GB flash included just wasn't big enough so I got a SSD and basically followed this tutorial: http://www.parkytowers.me.uk/thin/hp/t5740/mods_glenn.shtml. The only difference was the SSD drive I got (on sale with rebate at Fry's for $29.00) is an all plastic body, so I didn't even really see a need to mount it. I just stuffed it into the case and it worked great! Figured I'd pass along what I learned and thanks for the thread to give me the idea!
