Lenovo H420 (7752-1YU)


The Lenovo H420 (7752-1YU) is more expensive than the bargain-basement systems, but it makes up for it in useful features.

HDMI out. 6GB of RAM. Big 1.5TB drive. Integrated Wi-Fi. Core i3 processor. No bloatware. Rubber cushioned fan.

No USB 3.0. No free DIMM slots. Low-capacity power supply unit.

Lenovo H420 (7752-3FU)


The Lenovo H420 (7752-FU) is a decently-equipped machine for under $500. But not much else stands out on this budget desktop.

Great price. 6GB of memory. HDMI-out. Free of bloatware.

Weak power supply unit. No Wi-Fi. Only two memory DIMM slots. No USB 3.0.

Hardware Glitches


I'll spend the extra $100 and go back to building my own computers. BuBuy Le No Vo.

It is a Lenovo. but between this Lenvo and the last 7 I put into operation I think the "Lenovo" designator will be in the "CONS" section below

After ordering and configuring one of these machines it bacame obvious why purchasing the components alone would have costed slightly more. This is a refurb / glitchy computer. Wired network card has 20% dropped packets to the router located 15 feet...

Cmon People!!!


You cannot give this 1 or 2 eggs based on the fact your older programs will not work with Windows 7. That has nothing at all to do with the system. Also, do not give 1-2 eggs based on the fact you think its too big - these are the stupidest reviews I...

Not bad once you put Win 7 Pro on it


I bought 3 of these to update some older machines in the office.These machines are relatively fast, have good storage, and a decent amount of RAM for the money. The best part for me it the IBM driver disk that gets the machine up and running quickly of...

Excellent for price


Bought two of these for our company since it has the 1156 chipset that will allow it to be upgradeable in the future allowing this computer to last longer in our system than a Dell. And the cost was wonderful!!

speed, ease of set-up, cost

Wish it came with the trial version of Office 2010

lenovo H420 (77525GU)


Quiet--you cannot hear it run. When it failed after 18 hours of use New Egg stood behind the product

It is rather large. That issue I could work with, but it lasted only 18 hours and then the hard drive failed. I was not impressed
