Here are the current system specs:
HP Pavilion 750n
Pentium 4 1.60 GHz processor
80 GB IDE hard drive
512 MB DDR RAM
4 USB 1.1 ports
1 Firewire port
2 serial ports
1 DVD drive
1 CD-RW drive
1 floppy disk drive
v.90 internal modem
onboard/integrated video (I think), audio, and ethernet
I want to upgrade to at least 640 MB RAM, but I'm going to try for 1 GB.
I want to add 2-4 USB 2.0 ports. I don't know if I'll remove any of the 1.1 ports.
I want to add a TV tuner card.
I may have to replace the hard drive. The new one would probably be between 80-320GB.
I'd also like to get an external DVD-RW drive.
I'm not sure whether I'll be able to do all these upgrades. I'm probably a lot better off if I just buy a new computer. But I just want to be prepared in case I can do all the upgrades.
Any thoughts on what watt PSU I should get?
