Version Number?

Hi I've got a PAL PS2.
The code on the box is P-27202752-9
Anyone can tell me which Ps2 version I have?
And what is the best modchip for my sweetie???
Hope someone can help me.
Tnx a lot
Krusty

can u open the ps2 up and please say the bios number and the scph number on the back of the ps2

I haven't opened yet...cause I don't want to void warranty until i buy a modchip.
The number is SCPH-30004 R
Tnx a lot

u most likely got a v5 v6 messiah 2 and dms 3 would fit u best :)
