iMac G5/1.8 20-Inch
Here you can find the exact specifications of this Mac, along with guaranteed compatible upgrades for it
.
- Model: iMac G5
- Part Number : M9250xx/A
The MPN (Marketing Part Number), also sometimes called the model number, marketing number, order number or part number. This is the part number under which Apple sold this particular Mac model. Only base configurations have part numbers, while Macs sold with various build to order/configure to order options do not have them. What we consider a single Mac may have multiple part numbers, which may refer to different specifications of RAM, drive size, or case colour that were offered as base options. Part numbers also differ by country or region.
In modern Macs it is usually an 8 or 9 digit code, with the last 2 characters being "/A" or occasionally "/B". The one or two characters immediately before the "/" depend on country or region - "B" is the UK, "LL" the USA, etc. We represent this portion as "xx".
- EMC Number : 2008
EMC numbers cover a narrow group of Macs, or sometimes an individual machine. There are exceptions, but usually models that share an EMC number were released at the same time, and share all attributes apart from minor differences in CPU and other internal components. In a very few cases, Macs of the same model were sold with multiple different EMC numbers.
The EMC number is usually a 4 digit numerical code, though in a few cases there are additional characters.
- Model Identifier : PowerMac8,1
Model Identifiers often cover a narrow range of Macs. Usually one particular type of Mac, with a specific screen size, released at a particular time. Though in some cases a later revision that is substantially similar, will carry the same Model ID.
Staring with the Intel Macs released in 2006, Model IDs were in the format MacNameX,Y where MacName is a recognisable Mac model (iMac, MacBookPro etc.), and the X and Y are numbers.
However in 2022, a couple of years after the ARM switchover, Apple started using the format MacX,Y - the X and Y are numbers, but the "Mac" is the same across different models.
Old pre-Intel (PowerPC) Macs were almost all PowerMacX,Y or PowerBookX,Y (the exception being the very first iMac, which is: "iMac,1").
- Model Number : A1076
Model numbers, also sometimes called family numbers, are an identifier that often cover a fairly wide range of Macs. In cases where the fundamental design of a Mac has remained mostly unchanged, but incremental upgrades have been made to internal components, a single Model Number can cover more than 20 individual Macs, released over several years. Other Model Numbers are unique to a single machine.
It is usually a 5 character code in the format AXXXX, where the Xs are numerals. Some very old Macs have a Model Number that starts with an "M" rather than "A".

Compatible Internal Hard Drives & SSDs for this MacInternal Drives: click for more detailsThe hard drive or solid state drive is where all your documents, data and applications are stored permanently. Below this box are all the drives we do that are guaranteed 100% compatible with this Mac, based off the Serial Number or Model ID that you have selected. The list below is divided into sections for the main types of drives, which can include:
For more details on the differences between these drives, please see this post on our blog. With most Macs there are lots of options for having more or faster storage, and many can take multiple drives so you can mix and match SSDs and rotational hard drives to find your ideal combination of size, speed and budget. Some Macs have more than one main drive bay, and many Macs can use our range of caddies to replace their DVD drives with additional hard drives or SSDs. Some Macs also have additional drive bays that can be used with a mounting kit. If you have multiple types of bay in this Mac, you can select them with the grey tabs below this box. It is very important with all system drives (that is, a drive that you boot from) to leave a good amount of free space to allow the system to work well. We recommend leaving around 20-30GB of free space on the system drive, The closer you get to full on your system drive, the slower the Mac will perform. A 1TB drive can hold:
All drives come blank and will need to be formatted (erased), and if they are to be a boot drive, have an operating system installed. There are a variety of ways of restoring your data, either through time machine or by cloning. We sell drives, tools, enclosures and cables for you to do the work at home (see the "Cables, Adaptors & Tools" tab above), or you can send/bring your machine to us for us to do the work - prices all below. However you do it, you can be sure you are getting the correct part with our 100% compatibility guarantee. |
