Both Promise and Maxtor supply PCI IDE cards which will allow connection up to four extra drives. Just bear in mind that the PSU which came with your PC will only have limited output. If you keep adding extra drives you will have to increase the PSU wattage and also increase the cooling. Hard drives get hot.
thanks .... PSU: one thing though i bought a 400 W PSU a while ago, it tested with both intel and AMD, however the PSU worked with an AMD machine but when i tried it with my intel ... i got a power light but it wouldnt turn on ... any ideas why that would be? click here This is also another possibility then id need case fans?
Space forfixing drives to case: im also planning on adding a third optical drive (A DVD+-RW) but another problem is space in my case .. you guys have any recommendations on alternative ways to mount hard drives? and additional case bolt on? or an external way? id still want them connecting through the Pci Card though.
I have three hard drives (Total 200gb) two cd-rw one dvd +- rw one zip drive one floppy drive one creative live drive one pdi tv card one pci soundblaster card one agp video card one pci usb 2 card one pci network card one pci 1394 host adapter & 4 case fans running off 550watt psu no probs.
