Be sure to buy a pair of 65 nanometers. Double 65 nm depends on whether the power supply is 150w, but the production date of the main engine, and now the new products are all machines in May and June of 2009. Don't buy anything that varies greatly from month to month.
It is required to brush the machine on site and provide the original key, which makes the machine safer. And even small shops don't have this technology. Ask about after-sales service. There is no charge for software upgrade.
If you are a novice, I'll give you some tips:
1. Finding a store with good credit is the eternal truth. If the store is willing to sell you a fake, you can't help it. Generally speaking, the low price is fake.
2. After-sales technology, free upgrade. Ask clearly, so as to save more money in the future.
3. Brush the machine on the spot and buy things clearly. Ordinary shops do not have the technology of on-site brushing. Machine system calibration, USB pre-calibration and host system calibration. This is very important! If it is on-site painting, there are codes in it after disassembly, which is also correct. There is also packaging alignment, which is rare, but there are still some (stores usually have several sets, which may need to be booked). It is important that all printers on site have original keys. There is also a 1.6 startup disk.
4. The codes on the handle and the handle packaging bag must match.
Now it's a double 65, so you don't need to buy a cooling fan.
6. The machines before version A of the memory card are all 256M, and the latest machines are all 5 12M. Be sure to ask. 256m is about 80 cheaper.
7. The handle only says that the packaging bags must be matched. There are few brand-new handles now. Plastic packaging is generally refurbished. But you can buy a handle that can be disassembled directly in the machine, and the size is just right. The original wireless handle must be a Y-shaped screw, which can be compared. The original factory handle is about 300 wireless. The original wired handle is not easy to find. Wireless also has a plastic package with a receiver, and it must be original (directly from Microsoft, with a drive disk) of more than 300.
8. Number eight. The HDMI cable is about 90% of the original 360. But there are also a few TV sets that are not compatible, such as one of Samsung. You can also buy PS3 original HDMI cable, which is a little more expensive, about 120.
9. Hard disk, you can buy a 120G hard disk box with components, about 400, if you want the original box, about 450.
