14 Reasons For

A Best Selling Computer

The X51 is a popular choice of personal computer according to sales data from Amazon.

64-Bit Processor Operating Mode

This desktop computer supports a 32-bit|64-bit processor operating mode, which is typical of many comparable spec computers that were launched more than a year ago.

Chart Edit

Six USB 3.0 (3.1 Gen 1) Type-A Ports

The Alienware X51 is a six USB 3.0 (3.1 Gen 1) Type-A port personal computer. Most of the other personal computers that have been available for more than a year have between one and seven USB 3.0 (3.1 Gen 1) Type-A ports.

Chart Edit

Good Brand

Alienware medium processor core PCs have good reviews on average and across all personal computers Alienware is one of the superior manufacturers.

Quite Big Internal Memory

The smallest internal memory of PCs that were launched more than a year ago is 2GB, the biggest is 64GB, and the average internal memory is 8GB. With an internal memory of 8 gigabytes, the Alienware X51 has one of the bigger internal memory amongst comparable spec PCs of this age.

We compared this personal computer to all the other 8GB memory computers and we think the HP ProDesk 600 G1 ($1,465.28) which is cheaper is also worth considering.

If you are looking for a bigger internal memory then you might also want to look at the K31AD (12GB and cheaper), or the M32AD (16GB and cheaper) both from Asus or the Acer Aspire X3-710 (12GB and cheaper).

5 Reasons Against

Only HDD Storage Medium

The storage speed of this personal computer is HDD, which is typical of many medium processor core PCs that have been on the market 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.

We think you might also be interested in some of the other HDD personal computers currently available including the HP ProDesk 400 Mini which is cheaper.

If the storage speed of this personal computer is not fast enough for you then you might want to look at the OptiPlex 7020 SFF (SSD), or the Precision T1700 (SSD) both from DELL which is also cheaper.
