ooh, SGI what model has u? *drooling*

I once had a junkload of parts of an SGI Iris/4d with some key pieces missing, like the chassis and PSU

So what I did is I constructed a mechanics to house it in, using old BTS chassis rack and sheetmetal. Fairly impressive thing measuring about 60cm*60cm*80cm high tower.

The PSU proved a bit difficult since the mainboard and geometry engines draw about 250A on the +5V supply line under a heavy load and the voltage should be fairly stable and not droop too much under the draw.
Luckily I was able to repurpose a BTS PSU system to feed the beast.

The chassis was large enough to hold the mainoard and 9 blades (full-size VME cards) and also the dual ESDI drives sized like large garden bricks.

Wonderful toy, that. Too bad I had to get rid of it later due to my better half asking the crucial questions "is it useful at all?" and "where do you think you are putting it in?"
