If you're willing to look at something other than an AIO, then equill's suggestions merit serious consideration.
If you can get your hands on a Plus for free (or nearly so), then it may be worth a try. As a word processing machine, a Plus does a superb job (only seconds from first power-on to entering text). No internal hard drive, but an external one is easily connected. A Zip drive does perfectly serviceable duty as a hard drive replacement, and can often be scavenged for free as well. The combination is pretty quiet, so if noise is a consideration, this is about the best you'll do.
A Classic II can often be obtained for much less than an SE/30, so if you can find one, that's another possibility. Its narrower bus means that it's inferior to the SE/30 in speed, but the mere fact that it's an '030-based mac means that it will handily outperform a Plus or SE, to say nothing of the larger universe of software that you can run on it.
