Yes, indeed--it is 8 GB of memory, not 8 MB. That will be a good starting point, will probably upgrade later. Biggest factors for my work are hard drive access speed and cache, and main memory. Video board isn't that relevant, and neither is processor speed--those are things for "gamers".
The 2 x 2TB SATA drive suggestion is solid, and sound, but something for the future. The 2TB drives in enterprise class are nearly $300 each at the moment, which would add a hefty chunk to my final "assembly cost". Will file that for future reference. The RAID feature is nice, though believe it or not I've never had a hard drive failure--usually because I buy drives that are robust and not state of the art, and don't keep them near to their MTBF rating. It is a program that has worked for about 25 years...
2TB is, at the moment, is more storage space than I can envision. Even the single 1 TB drive I bought, absent the OS and Apps, will only be about 20% full with everything I have. Growth is slow...
I do have 2 external drives for backup, from the Pagoda Book.
Not the largest or fastest [now] but not at the end of their useful life either.
The virtual box link was interesting, and I'll investigate further. Again, sound advice. From what I've seen of Bootcamp it looks a lot simpler than virtual box, but that's just an instant assessment, not necessariliy factual. Problem is I have to find bootcamp--it is supposed to be in the utilities folder of OS-X but did not show up on my daughter's update. Hmmm.
The reason for the bootcamp was other sound advice I received--"don't run parallels, or run any Windows apps in a virtual machine or under OS-X. Keep it all separate and distinct, and keep it all on a separate bootable hard drive." No bad consequences were offered or suggested but the separation makes some kind of sense.
I'll be putting most of the Mac together today, as the final part arrived yesterday--the keyboard! I'm really curious to see how fast that SSD drive will be!
