I keep toying with the idea myself, when I get the cash together, which hopefully will be soon before this old wreck packs in

There are few standards though and a huge choice of parts - all a bit of gamble whether it'll work or not. Just don't fancy wasting money like that - would much rather go for a pre-built to my specs system.
This part will work with that part but only with this other part but your system will be faster if you just use this other part instead, but that...
