As long as you terminate the windows installation on the Dell, you can transfer your license. And downloading an ISO for Windows isn't pirating because you would use the license granted to you by Microsoft (the one that came with the Dell).
No, they told me this cannot be done.
I'll just get a new OS. It's fine, so, this is my final list:
NZXT Apollo Black SECC Steel Chassis ATX Mid Tower Computer Case
OCZ StealthXStream OCZ500SXS 500W ATX12V / EPS12V Active PFC Power Supply - Retail
HIS Hightech H467QS512P Radeon HD 4670 512MB 128-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ
GIGABYTE GA-EP45-DS3L LGA 775 Intel P45 ATX Intel Motherboard
Intel Core 2 Duo E8400 Wolfdale 3.0GHz LGA 775 65W Dual-Core Processor Model BX80570E8400
Extras:

Will all of this be compatible with each other? Please look very carefully, I have and I think it'll all work but PLEASE make sure I'm right... I can't afford to be sending things back. Thank you so much!
