First off- Jeez, I hate HP's. Okay- I have a HP m7640n with a bad mobo, replacing it with a very basic mobo MB FOXCONN M61PMV AM2 GF6100 RT (cheapest on newegg), which works for me, 'cause I am dropping a 9500 Phenom in there with it, but the problem I am having is... no firewire plug on the mobo to attach to the case's 1394 built in plug. So, I looked at newegg again, and it seems that all the affordable firewire pci cards that they have, have a internal connector that is a firewire (described as a 6 pin)plug also... where my plug is a 9 pin, usb type plug. So my question to you all is... adaptors, better 1394 card, why did you buy a HP? Actually the last part is easy, $50 for every thing except a working motherboard for use as a kid's/ 2nd computer...(no, they don't touch my laptop).Any and all suggestions!
