Unsure about Xbox Revision. 1.5?

Hello, so i found my old xbox, now i'm not sure what revision i've got i looked up the wiki and got some contradicting information and i think it might be a 1.5 and the wiki told if its a 1.5 i should post about it here

​

i will list all of the points i checked after looking at the wiki

my MFG Date is 2003-08-11 so it should be a 1.4 or a 1.5

the Serial number is 5030992 33305 which would also fit the 1.4 or 1.5

but the dvd drive is a thomson and the wiki says that only 1.0 or 1.1 revisions got thomson drives

the kernel is 5101 and a 10gb seagate hdd by the way

​

i would try to check the lpc thing and the videochip but i'm a complete noob to console mods and dont want to break it while taking it apart is there another way to check or could some link a idiot friendly tutorial on how to get tothe motherboard?

​

edit: i also want to mention that this console was never refurbished or even opened before. so everything inside it should be factory:
