a. Able to find the parts.
b. Really great at solder work.
c. Able to find what else was left out.
If you can do this, then move ahead.
In closing, such may be a feature of the board but such can be dropped to save a few bucks on the way to making a cheaper machine. eMachine and others will do this and drop the feature from the product sheet.
I have a emachines t5020 with an Intel 915GAG motherboard. Intel's website says this motherboard has a PCI express x16 slot. However when I opened the case there was no slot to be found. The architecture for the slot is there, but no slot for the card. Is there any way to add the slot?
