4 Reasons Against

Alienware PCs Only Have Unexceptional Reviews

We assessed average ratings for each PC manufacturer and found that whilst Alienware has unexceptional average ratings across all computers, Alienware has good ratings specifically within its medium processor core personal computers range.

Only HDD Storage Medium

The storage speed of this computer is HDD, which is the most commonly found storage medium on medium processor core personal computers that are a similar age to 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 compared all the other HDD desktop computers to this personal computer and we think cheaper PCs such as the HP Z230 (£669.57), the DELL Precision T5810 (£898.80), and the Lenovo H50 (£891.49) is also worth considering.

Personal computers with a faster storage speed that might also be worth considering include the EliteDesk 800 G2 SFF (£1,337.94) (SSD), or the ProDesk 600 G2 SFF (£799.63) (SSD) both from HP or the Lenovo Thinkstation P500 (£1,236.87) (SSD).

Only Has One Memory Slot

The number of memory slots found on the Alienware X51 is more than most personal computers of a similar spec and age to it. The most commonly found memory slot is 4x DIMM, but this memory slot is not found on this desktop computer. The memory slots 2x DIMM are also found on this computer.

Chart Edit

Only Two USB 2.0 Ports

The Alienware X51 is a two USB 2.0 port desktop computer. Most of the other computers of this age and type have between one and nine USB 2.0 ports.

Chart Edit

2 Other reasons to consider the Alienware X51

Released Over a Year Ago

It was over a year ago when Alienware released the X51.

Average Internal Memory

With an internal memory of 8 gigabytes, the Alienware X51 has a relatively average internal memory compared to most of the other PCs of this age and type.

Other 8GB memory desktop computers currently available which you might want to look at include the HP Z230 (£669.57) which is cheaper.

If you would prefer a PC with a bigger internal memory then you might want to look at the HP 810-477na (£939.99) (12GB), the DELL Precision T5810 (£898.80) (16GB), or the Alienware X51 (£1,099.00) (16GB) which is also cheaper.
