I am admittedly somewhat of a novice but wish to convert one of my older Dell computers to a WHS machine. I have a choice of using a Dell 4550 or a Dell 8250. I have purchased two Seagate Barracuda SATA XT 2 TB hard Drives (model 9GV168-301). I have purchased a SATA II NCQ Host controller card that supports 3.0 GBPS and NCQ, 32 bit @33MHZ, PCI rev 2.2 compliant with buss metering modes. I have all the cables etc.needed. My first question is; am I on the right track so far? If yes great, if not what to fix. Next what primary hard drive would you recommend, size speed. brand etc., as I will replace the original hard drive to something bigger? I also have purchased Microsoft Win home Server pwr pk 3 win 32, OEM System Builder Pack. I can install any amount of memory as needed as I have spare 512 and 1 GB spare mem. modules for each machine. Any and all suggestions are appreciated for choosing either dell machine(4550 or 8250) or a primary hard drive recommendation, software install or watch outs, partitioning etc. , hardware install sequence, Bios settings etc. Thanks alwayslrnin
