Pros: This thing does not get Hot!! Amazing HD video playback ability!

Cons: Takes up 2 slots

Overall Review: Using on old P4 3.0 Gig processor with hyper threading I am still able to YouTube 1080P full-screen videos with very little to no stuttering!

Pros: Small case. Good as just a basic desktop.

Cons: Gets very hot inside and mother board caps usually blow their tops with in 3 or 4 years of being new. They can be rather loud due to the front fan when the machine is under heavy load.

Overall Review: I have owned about a dozen of these since they were brand new, so this is not a critic of this (refurbished product) unless the motherboard caps have not been replaced. They work well with Geforce 510 video cards due to the week power supply. They are rather picky about what ram you put in them. I have never gotten them to reconise more than 4 Gigs at a time. Specs say it can take 8 Gigs. When they were new the bios had an option to turn on AHCI which would be great for using SSD's in them, but over time Lenovo decided to remove the function through "bios updates".

Pros: Flexible powerhouse! Lots of ram expand-ability. Xeon options. The Vendor dose an excellent job of packing these!

Cons: Bios is very sensitive to trying to activate UEFI bios settings with non UEFI video cards (it just so happens that these pc's come with NON UEFI video cards. Any modern video card will fix that. (cheep Gforce 710) These use Server RAM! ECC

Overall Review: Know what you are getting into when you buy one of these!

Pros: M2 and ssd options, durable, can be used with a docking station

Cons: you can only use an M2 or an ssd drive. They both use the same location. :( The probook 450 G3 series will let you use both but does not have a docking station option.

Pros: It comes with an extra power supply which I find handy for using my old dell soundbar under a non dell monitor. This bar seems a little better built than some of the other Dell bars I have bought in the past.

Cons: It is still just a sound bar. You turn it up too high and you get distortion.

Overall Review: It is perfect in the office where you need to here your voicemail messages but are not planing to listen to a rock concert ;)

Pros: It is simple to install. It is FAST!!!!

Cons: Hard to know which pc's will allow you to boot from this.

Overall Review: Even if your pc can not boot from this device, it makes a super fast second drive. It is even recognized in my old HP Elite 7900 and 8000 using the 4x slot. If you use the 16x slot it is even faster! I used a Samsung 960 evo for testing.

My first unit was bad and they were very flexible as to how to get me a replacement!

Good flexible desktop. I always add an m.2 drive for the OS. Lots of expansion ports. Have been using HP Elite series for about 8 years now. So much better quality and longterm support (bios updates, etc) than the compition.

It is just what is it described as. Shipping was fast!
