unless you have a high end unit you have a single 12v rail, and it should have over 18A on it
in addition the unit should be from a good maker
in addition consider casing, the components you've selected will get hotter than a Pentium 3
the hard drive should work fine, as long as the board has 2 IDE channels (so the optical drives go on 1 and the PATA hard drive goes on the other)
My dad is looking at upgrading our current PC (old P3 Windows 98 machine), but doesn't want to spend too much. So I've been looking at a budget upgrade, and wondered if this PC sounds all right/will work etc.
