Who on earth would cannibalize parts from this rather than just buy new...? (admittedly the big caps are nice Sanyo units)

Looking at mine:
TC4: 16V 2200uF
TC8: 6.3V 2200uF
TC9: 16V 220uF
TC11: 16V 2200uF
TC12: 16V 220uF
TC13: 16V 220uF
TC15: 6.3V 2200uF

I'm not too hot at identifying inductors or SMD resistors, so here's some pics instead:

Maybe someone who realized that the board is broken beyond repair?

Whats the exact Name of this Board ?

Thanks

Matthias

It looks like the same board used in HP T5700 thin https://www.parkytowers.me.uk/thin/hp/t5700/

It's from an HP T5700 thin client.

48.3B201.011 turns up results for Acer thin clients as well.

Thank you, this is beyond great, I'm forever in debt! It'll be a few days until I have enough time to tinker with it, but I'll update the thread whatever the result.
One more question, is there something connected to the header marked "TDM" (near the ATi Rage chip)?

I have bought/received quite a few cannibalized boards, all proved to be working after repairs: LuckyStar P5MVP3 with all big caps removed, some thin traces destroyed in the process; ATC-1425 missing a few electrolytic caps and quite a few smd ones and resistors, motherboards without BIOS and KBC chips, GF4Ti4200 without the two big inductors and so on... Of course this doesn't say a thing about this board, but I'm hopeful.

No other markings on it except what you can see on the photo, sorry.
However here I found it described as Acer P558 M/B 02157-1 48.3B201.011 Thin Client mITX Motherboard TM5800 733MHz CPU

Nope, at least not on mine.

The inductors are low pass filters, removing high frequency ripple. Anything reasonably similar in terms of winding length, turns, coil area, wire gauge and core material should be close enough and do the job. Basically, if they look identical, they'll be electrically identical too. Also, it's not all the world if the inductance is a little bit off in that application. Perhaps you could even get away with a simple jumper wire as replacement.

Edit: here's an explanation of factors affecting inductor properties.

R410 is a zero ohm resistor. It's basically a jumper in a package that a soldering robot can handle. Can be replaced with a solder bridge or a piece of wire 😀

Well, it works. Thank you again dionb. Now I'll have to find some use for it.
What I find amazing is the amount of heat this CPU generates (or rather doesn't). The original heatsink and spring clamp are missing, so I've used what you can see in the picture, attached only with a dab of thermal paste. Barely gets warm to the touch.

Great! Now you have the same problem I do 😉

(don't bother with OS/2 Warp4 - although if you do and get sound working, please do share solution!)

That was quick. Nice going.
