Yes, what you want is feasible.
Now, I don't run Macs, and won't have anything to do with that monopolist's kludged PCs, however, the website that you referred to does seem to prove that a NTFS machine can be used as a server for a Mac.
The performance hit on the host server is a matter of speculation. I would time back-ups for down time on the server machine. You may be able to play games in the foreground, but depending on the load on the CPU n the game you may see a significant performance hit.
Yes you can use different HDs for storage. I boot off a 128 GB SSD, use a 640 GB WD Caviar Black for (Some) games and apps, and have two Seagate 1.5 TB, two Samsung 2 TB and a Hitachi 3 TB for server purposes. You can run the NAS directly from Win 7. I bought all of my HDDs before the Thailand flood.
Getting this in under your budget will be a challenge depending on your HDD and GPU. You are looking at: $220 CPU, $50 + for a case, $125 + for a GPU, $100 + for the OS, $100 + for the mobo, $200 + for the HDD(s), $125 + for the SSD, $75 + for the PSU, $20 for a DVD, etc.
