I recently bought an HP thin client t5720, but had really hard time finding a PCI expansion module. I noticed that there're generic PCI riser cards readily available with 3 different lengths (2.5cm, 3.5cm and 4.7cm) but I can't figure out which to buy (can't be the 2.5cm one though).

I've also read that capacitors are needed to be soldered into the official PCI expansion module in order to get it to work with some cards like AOpen Cobra AW744L-II (which is the card I have). But with those generic riser cards there's nowhere to solder in capacitors. Can I scratch the pins a little bit and give out some copper and add caps? If so, where should I add them?

I can measure my original riser later today. I'll write the height of it here then.

I also have this card, and was planning on installing it into a SFF desktop I just ordered, which uses a PCI riser card. Can you point me to where you read about adding capacitors to PCI riser boards?

The official PCI expansion module w/ PCI Riser for HP Compaq t5720 Thin Client card (and expansion cover) are available on ebay for $19 plus shipping

The seller does ship to China.

I read it here, but I don't think it will be affected if you're not using t5720 or maybe t5710.

I got the machine itself under $10, the official expansion module would cost more than 6 times than the machine itself including shipping...

I ordered a Yamaha Waveforce 192XG (YMF724), which is confirmed working with t5720.
