+4 More reasons for
3 PCI Express Slots Version
This desktop computer supports a 3 PCI Express slots version, which is typical of many comparable spec personal computers that have been on the market for more than a year.
Two PCI Express X1 (Gen 2.x) Slots
The Lenovo ThinkCentre E73 is a two PCI Express x1 (Gen 2.x) slot personal computer. Most of the other medium processor core computers that have been on the market for a similar time to the ThinkCentre E73 have between one and two PCI Express x1 (Gen 2.x) slots.
The widths of desktop computers of this type and age range from 33mm to 510mm. At only 160 millimeters, the ThinkCentre E73 is fairly narrow compared to most of the other medium processor core computers that came out around the same time as the ThinkCentre E73.
15 Reasons Against
Quite Slow On-Board Graphics Adapter Dynamic Frequency
With an on-board graphics adapter dynamic frequency of only 1,100 megahertz, the ThinkCentre E73 has one of the slower on-board graphics adapter dynamic frequencies amongst desktop computers of this age. Across all the medium processor core computers that were released more than a year ago the on-board graphics adapter dynamic frequencies range from 700MHz to 1,300MHz.
Quite Slow Processor Clock Speed
Computers of a similar spec and age to the ThinkCentre E73 have processor clock speeds of between 1.3GHz and 4GHz, and the average processor clock speed is 3.1GHz. With a processor clock speed of only 2.8 gigahertz, the ThinkCentre E73 has one of the slower processor clock speeds amongst medium processor core computers of this age.
Computers with a faster processor clock speed that might also be worth looking at include the Lenovo S500 SFF (2.9GHz).
Only HDD Storage Medium
The storage speed of this PC is HDD, which is the most commonly found storage medium on similar spec PCs that have been around for around the same time as it. A Hard Disk Drive (HDD) is the traditional storage method for computers. A HDD stores the information on magnetic disks. HDD drives are cheap, but they are slower than Flash and SSD bases storage systems.
Computers with a faster storage speed that might also be worth considering include the Fujitsu W530 (SSD).
Very Small Internal Memory
The smallest internal memory of medium processor core computers that have been available for more than a year is 2GB, the biggest is 64GB, and the average internal memory is 7.8GB. The ThinkCentre E73 has one of the smaller internal memory (only 4 gigabytes) amongst PCs of this age.
If this Lenovo personal computer internal memory is too small for you then you might want to consider the DELL 270 (6GB).
+12 More reasons against
Quite Small Hard Drive Capacity
The ThinkCentre E73 has a quite small hard drive capacity (only 500 gigabytes) compared to most of the other PCs that were launched around the same time as the ThinkCentre E73.

Only 11 On-Board Graphics Adapter DirectX Version
This computer supports a 11.1 on-board graphics adapter DirectX version, which is typical of many personal computers that have been around for more than a year.
Only Has One Memory Slot
The number of memory slots found on the Lenovo ThinkCentre E73 is more than most medium processor core computers that were launched more than a year ago. The most commonly found memory slot is 4x DIMM, but this memory slot is not found on this personal computer. The memory slots 2x DIMM are also found on this desktop computer.
Only One 3.5" Bay
The ThinkCentre E73 is a one 3.5" bay computer.
Only Two USB 3.0 Ports
The ThinkCentre E73 is a two USB 3.0 port desktop computer. Most of the other comparable spec PCs that came out around the same time as the ThinkCentre E73 have between one and eight USB 3.0 ports.
Only One 5.25" Bay
The Lenovo ThinkCentre E73 is a one 5.25" bay desktop computer.
Only One DisplayPort
Most medium processor core computers that have been on the market for more than a year have between one and three DisplayPorts, including the Lenovo ThinkCentre E73 which has one DisplayPort.
Very Small Maximum Internal Memory
With a maximum internal memory of only 16 gigabytes, the ThinkCentre E73 has a quite small maximum internal memory compared to most of the other desktop computers that have been on the market for more than a year. Across all the computers of a comparable type and age to the ThinkCentre E73 the maximum internal memory range from 2GB to 520GB, and the average maximum internal memory is 33GB.
Quite Small Processor Cache
At only 6 megabytes, the Lenovo ThinkCentre E73 has a fairly small processor cache compared to most of the other desktop computers that came out more than a year ago. The average processor cache of PCs of this age and spec is 6.6MB.
Only Four Processor Threads
The Lenovo ThinkCentre E73 is a four processor thread desktop computer.
Quite Slow Maximum Turbo Frequency
The maximum turbo frequencies of medium processor core computers that have been around for more than a year range from 1.8GHz to 4.4GHz. With a maximum turbo frequency of only 3.3 gigahertz, the Lenovo ThinkCentre E73 has one of the slower maximum turbo frequencies amongst medium processor core computers of this age.
