I'm surprised no other comments (well, that I saw) picked up on that. While it's not impossible for a 486MHz machine to have shipped with those specs, it sounds more like a late high-end 486 system- especially the video. Well, I guess all of it actually. 486MHz would have been K6-2/3 (overclocked) or (overclocked) P2 or P3, and most of those systems shipped with hard drives over 1gb, and more than 32MB RAM. I think not having a CD-ROM and especially NO USB points toward it being actually a 80486...
If it's a 486 CPU, even if it's something 'nice' like a DX4, it's probably not worth it. Unless you really have a very good reason... Redhat 6 or earlier works pretty well, I used to have a really decent Redhat 6 server setup on a P100 with 64 MB RAM but considering how cheap you could get other hardware for, unless it's for some proof of concept of the re usability of hardware from past eras, it's really going to be a pain.
