    The one recommendation I got from Powerleap was for a Celeron 733,
    which they had at the time, but they were very noncomittal about it
    working. And it remained far too expensive for such an old system.

    I actually ran the Intel Multia/Powerleap at 400MHz with a tall cooler
    and high volume cooling fan. That would not fit in the case.
    Powerleap also provided a very low profile cooler (at my request),
    which proved unusable at over 233MHz. I installed a low profile all
    copper cooler with fan which allowed me to run without cutting the
    case, but limited the reliable speed to 333MHz when closed, and 366MHz
    with the lid off. I didn't want to cut the lid to fit a tall cooler
    at the time, though in retrospect I could have either drilled a grille
    pattern over the CPU, or cut a hole and installed a wire grille, then
    used foam tape to 'seal' the fan to the lid. Wasn't worth it for the
    10% increase in speed. I had opened up the grille on the side where
    the stock fan exhausted to improve overall airflow.

    I did also attach a small aluminum heat sink to the video chip, which
    ran blazingly hot, using double face thermal tape. It helped (no
    screen jittering after long runtimes).

    The box was very reliable (as far as any box running windows is) and
    usable with NT for browsing and 'general' nongame purposes. It has
    long since been ebay'd.

    Still have two Alpha UDBs on the shelf that I need to decide what to
    do with...
