Hard drives aren't that hard to put in. I've had Western Digitals and Maxtors and they both came with a set up disk. The disk has step by step instructions to format and partition the drive. If your going to upgrade the motherboard you may have to get a new case. I found a pic of the 8100 and the back doesn't look like a standard ATX board would fit. But if you upgrade the case your options are wide open. Pretty much any motherboard and powersupply will fit in a standard case. If you upgrade the board you may not have to get a power supply. I checked out some specs on the 8100 and it says it has a 330w supply. So if thats true you may be in good shape. It will just depend on what kind of board connector it has.
