The original issue was about having it all set up on a hard disk, then moving that to a new machine with new hardware. So the problem there would be whether XP could "survive" the move.
OEM is a source of confusion. There's been OEM version Windows, Full version, and Pro version in the past. The typical prices were about $100/$200/$300. (At least they have been in the past. I just took a look at a reseller site and they seem to have prices all over the place, with a lot more variations:
64-bit only vs 64/32, key only with no disk, etc. I guess both the licensing and the value of a Windows disk have been getting more flexible.)
OEM Home is licensed to be installed on only a single machine. It's the license that OEM builders use on most retail PCs. One pays extra for a "real" Windows license that can be installed on any number of machines, as long as it's one at a time. Pro can also be installed on multiple machines.
There was a court case a few years ago where MS was trying to stop the sale of OEM disks online. Since it was resolved, one can still buy an OEM disk but the seller must also provide a piece of hardware, as per the license -- any hardware. :)
Looking at buycheapsoftware.com I see that they claim to sell such a thing as "OEM Pro". I would guess that's Pro without a box or manual, but still licensed for multiple installs. I'm not sure, but from what you say it sounds that way.
The whole thing gets further confused by the effort of resellers to make the product look good. OEM Windows is often referred to as "Full OEM" while Full version might be called anything except "Pro". In any case, if one buys a "Full OEM" disk it will probably not activate if installed to a second machine with different hardware. If I were going to buy "OEM Pro" I'd want to see the license first to make certain that it wouldn't be limited to a single install.
