I'd buy an FGPA accelerator but it would have to be faster and have more memory than my Blizzy 1260
An IdeFix Express Mrk2 with SATA might be tempting if Jens every finishes it!
Not really interested in much else, and I don't think USB is really that useful on an A1200.
Sound cards are cool but again, not quite so useful on an A1200 (due to clock-port bandwidth and lack of space).
If I had an A3000 then I'd be interested in CPU/HD/GFX/SFX/USB upgrades
