Hey guys, I did an upgrade at a hospital cat scan computer at work and was able to take the old computers home. I'm just looking into my options to see if I could through $150-$400 into it and turn it decent video editing computer. The model is a fujitsu-siemens primergy 470 with (motherboard) system board D1031.
CPU: Dual Pentium III 800MHz
I/O Options: 32-bit PCI slots (5)(NOT PCI-E), AGP slot, Ultra-SCSI Wide interface, SCSI interfaces (2), serial ports (2), ATX power connecdtor, & RAID slot
RAM: 2GB of PC100 ECC SDRAM 168-pin DIMM memory
No way that can be turned into a video editing computer It doesn't have enough processing power.
If you want to spend 150$-400$, then you can get a A64 Mobo/CPU combo and if you don't intend on gaming, then you can get away with some cheap graphic card, since 2d performance doesn't vary much among different cards.
I have to agree with grahamnew82 in saying that the processors are too weak. If you willing to spend a bit over 500$ you can get an above average computer for video editing.
Here is a computer with good processing power for only 399$ @ TigerDirect.ca http://www.tigerdirect.ca/cgi-bin/ShoppingCart.asp?msg=
With taxes and S&H it should cost around 500$. It comes with integrated GMA but has a PCI-Express X16 slot if you feel the need for a good video card. Hope this helps.
