I decided to be prudent and skip the SSD for now. I do have a spare 250GB HDD I can make the boot drive for Win 7, but fitting it in to the case with the other drives already in there would be a pain.
Prob is I can't afford any downtime. If I was building a whole new system, I could have kept my current system as is while I gradually installed apps on the new one till it was complete and then decommissioned the present one. Now I'll have to dual boot on the same machine.
My current XP boot drive already has about 50GB space at the beginning that I had left when I last organized the disk. Win 7 was intended to go there. According to this thread,
dual booting XP and Win7 on the same drive is fairly easy.
I'm not an entire noob as far as dual booting goes; have done it with W98/W3.1, W2k/W98.
I'll image the current XP boot partition before I touch it, of course. I understand W7 may put its files on other partitions (I'll disconnect the other drives), but that shouldn't be a problem because this system will continue as is till I am able to build the new m/c in 6 months or a year.
What do y'all think?
