I always have a soft spot for unusual slim and SFF retro PCs, and when I saw this strange little Fujitsu Siemens "pizza box" when browsing eBay for badly described old PCs, I couldn't resist! Made an offer below the seller's asking price, but probably still paid slightly over the odds for what it is ...

It's an i845 based Pentium 4 in a kind-of-ITX type format, but with dual PCI riser card, slim CD-ROM drive, and space + connector for a slim floppy drive (which are available on eBay in the correct Fujitsu off-black with mounting bracket!). This one has a 2.4Ghz Pentium 4 and 512Mb (2 x 256) DDR RAM.

The PSU is by AC-bel (generally good quality for OEMs?) and seems half way between FlexATX and TFX formats - thankfully it has standard 20pin ATX connector + 4 pin CPU power, and checked out nicely with a PSU tester. I had a moment of thinking it was dead, but realised it will only boot with the "tamper" switch shorted. Remarkably (considering the period and the limited airflow) all the capacitors seem fine!
Any tips for removing the CPU cooler? I tried pushing on the levers, but they seemed very stiff, and I heard some ominous creaks! I'm sure it would benefit from re-pasting, but also sure I've seen horror stories of P4 coolers ripping off the CPU from the socket when removing a dried on cooler?
I'm hoping that the Intel 845G integrated graphics would do the job for most Win9x games, and with an SB-Live or YMF744, this little pizza box would do a good job of retro at my main desk - like a thin client type setup - but with original media drives.
