Lenovo ThinkCentre M55e


The name "Lenovo ThinkCentre" is familiar to millions of business users worldwide. The ThinkCentre M55e ($1,259 direct, $1,619 with 22-inch widescreen LCD monitor), continues the tradition of excellence for this desktop line that goes back to when...

Dual-core processor. Small form factor. Enterprise-class hardware. ThinkVantage utilities. Three-year on-site warranty

A bit pricey. Only a 90-day subscription for Symantec Client Security. DVD/CD-RW drive

The Lenovo ThinkCentre M55e works equally well in the enterprise as well as in small and medium businesses.

Lenovo ThinkCentre M55e Desktop


Very quiet, powerful, and light weight

Could have been a little bit faster

I am happy as long as it takes care of whatever I need to do.

A Good Bargain


So, the keyboard loses an egg and the 32-bit OS loses an egg. As someone who hasn't purchased many refurbished items in the past I would still have to say this is one helluva good bargain. I will however study the images and wording more carefully if I...

Cosmetically good; a couple of scratches on the bottom ; The build quality is exceptional. Everything works as it should. I will look very hard at Lenovo for future purchases ; The processing speed is an exceptional value

The listing was slightly misleading. I was expecting a Lenovo keyboard (I didn't give any thought to the mouse.) but a cheap Chinese made off brand usb keyboard was provided ; I also was expecting WIndows 7 Home Premium 64-bit, but the 32-bit version...

Awesome Computer!


This is a great machine! I haven't touched my laptop since I got it! It is super fast and just nice to use. Best purchase I've made in the past year

The only difficulty I had was in being able to read the Windows 7 product code because it was microscopically tiny! But that was all

Doesn't work off the box


No pros here since it didn't work off the box

Didn't work

Great value & highly expandable


Definitely a good value. Description is confusing, as it has conflicting specs: these are ThinkCentre M57 (not M55) machines, and have 2.3GHz (not 1.8GHz) Core2 Duo CPUs. I've ordered a dozen over the past year for my nonprofit company. A few of the...

Core2 Duo 2.3, 4 DDR2 slots, eSATA port, 8 USB ports, tool-free drive mounting. Windows 7/8 Aero-compatible video

So-so refurbishing job, occasionally missing chassis hardware (a few missing PCI-E covers, a missing optical drive bracket)

Good Little Computer, If it Works...


Ordered 2 of these at same time. One did not get past a power up checkout. Had to ship back to Newegg for refund, as no replacements were available. I was a little disapointed that a unit would ship and fail such a simple test. It's not like i had to...

Cheap ; Compact ; Windows XP

Old Processor ; Only 1 GB RAM

Got Only One


Faster than my 2002 HP new for $1000, LOL, had the 1st XP on it. Im glad the thing broke down finally or Id have missed this deal. Wish Id have bought 2, too late now.

Can save all my old stuff I didnt want to loose. XP PRO, beats out my 2002 Xp home. Even corrects spelling ! So its flat on desk, its a Pro 4 me cause its small and it fits under my monitor stand, Fits Perfect next to my Slimline. And info says I can...

Front DVD access bad, has flap in front of it so you have to push really hard on double button to do the drawer functions, Found that the flap comes down to fully expose the DVD, but then that blocks access to stuff under that, Removed Flap with...

Speedy Dual Core !


I love newegg! Fast shipping, Great deals you can't find ANYWHERE !

At first I thought the CPU clock at 3.4ghz was for a single core, but THIS IS a fast performing DUAL CORE CPU @ 3.4Ghz !!! This is a ridiculously awesome deal in hardware value and quality . Faster clock speed than my 2.4Ghz intel QuadCore. I use this...

None really! Just No HDMI out, VGA only. But has room for an HDMI upgrade
