Swapping the SSD from a BTO 2010 iMac for a standard HD and doing a RAID

Question

Does anyone know:
1) If it's possible to remove the SSD that comes in the BTO 2010 iMac without voiding warranty?
2) If yes to 1), is it possible to install a standard hard drive in that slot?
3) Is the SSD a 2.5 and the other hard drive a 3.5 form factor?
4) If yes to 1) and 2), and if we put a 1TB drive in each bay, is it possible to do a "striped" RAID with the two disks?

Answer 1

1) If it's possible to remove the SSD that comes in the BTO 2010 iMac without voiding warranty?
The answer to that is in the warranty. Here is what it says:
This warranty does not apply: (a) to consumable parts, such as batteries, unless damage has occurred due to a defect in materials or workmanship; (b) to cosmetic damage, including but not limited to scratches, dents and broken plastic on ports; (c) to damage caused by use with non-Apple products; (d) to damage caused by accident, abuse, misuse, flood, fire, earthquake or other external causes; (e) to damage caused by operating the product outside the permitted or intended uses described by Apple; (f) *to damage caused by service (including upgrades and expansions) performed by anyone who is not a representative of Apple or an Apple Authorized Service Provider (“AASP”); (g) to a product or part that has been modified to alter functionality or capability without the written permission of Apple; or* (h) if any Apple serial number has been removed or defaced.
2) If yes to 1), is it possible to install a standard hard drive in that slot?
