Title: Great Value Refurbs
Review: Great value for the money. Systems look good and are very clean. Ordered 2 units, both work perfectly and are spec’d as described.Will be buying a few more of these for sure.Edit: I have purchased about 10 of these so far (from a couple of different sellers but the same item listing) and as long as you keep your expectations in check, these are great value. They use some kind of huge decal/wrap to “cover” the case to hide scratches or markings, which is fine if they are applied correctly but I have received 2 recently that were just sloppy. Bubbles in the top/left side at the case lid, poor, trapezoidal cutout of the Windows logo underneath, and uneven cutting around the Lenovo logo. Where these are being placed, it don’t matter, but if this were visible to users/customers it might not be acceptable. To me, however, value is king and there’s more than enough value here to overlook these annoying cosmetic inconveniences.

Title: No cd/dvd included
Review: It’s OK. Didn’t come with a dvd drive, which is fine, but it was advertised as including one.

Title: Great value
Review: I have been using this computer for a couple of weeks now and it has performed great. I can’t get used to windows 10 after using windows 7 for years (why change what’s not broke), but the computer works great, at least up to now. Would definitely but again.

Title: Lenovo thinkcentre 900s
Review: I ordered one with a DVD drive in it. It worked as expected aside from not having the proper front panel and the DVD drive was noticeably removed the sata cables were still hooked up and In the empty DVD tray. The seller did try to make good by wanting to send an external drive but I wanted the built in drive and proper front panel. The refurbishment was of mid quality as the important thing was missing and the case is slightly damaged but is to be expected from a 7 year old refurbished PC. Did include a wifi USB antennae which isn’t great but it works. Easy to set up with windows 11 pro. It came with a keyboard and mouse but not Lenovo branded. Boot in 20 seconds which is normal and out of the box. A bit loud since it had random fans in it which brand ive never heard of.

Title: Does not work
Review: Computer does not boot up. Did not ship with an operating system. Something obviously rattling inside as well. Returning for a refund because Amazon customer service representative said that I couldn’t have a replacement sent out but I could have a refund.

Title: excellent value with some caveats
Review: I purchased this computer when they were listed for $89 earlier this month. Opened the box to find I had received a lenovo M710S SFF instead of the advertised M900. In addition, my specifications showed an i5-7400 instead of the advertised 6500. Oh well, others have stated they didn’t receive “exactly” what was advertised. Upon startup, the computer yelled at me with a four beep alarm referencing an issue with the memory. Popped open the case to find that the one RAM stick (ADATA 16gb DDR4 3200mhz) was only clipped into one side (I was saying “it only cost $89” a LOT during setup). Once it was popped in, everything booted up just fine. This computer will be replacing my old thinkpads duties (email, photos, etc) and in that regard, it is absolutely fine. I just ordered additional RAM and a low profile 1030 to throw in, and hopefully do some alright gaming on a budget. The included mouse is serviceable, and the included keyboard feels oddly satisfying despite being so cheap. included USB wifi module works alright but definitely throttles the traffic from my gigabit wifi.If you don’t mind it not being *exactly* as advertised, and have enough tech experience to fix some minor issues, this is a wonderful bargain for the price.

Review: *WARNING LONG REVIEW*For the price, I think this computer is actually really good. I had a graphics card(GT1030) and plugged it in right away, so I’m not sure how good the computer actually is for playing games without a graphics card installed, but I’ll just talk about the actual stuff it came with.Anyways, the computer arrived and worked with no problems, so that’s a plus. However though, there is no HDMI port, which is really my fault for not double checking.It came with a mouse and keyboard as advertised, and they work fine. The mouse has no scrolling issues and seems accurate so I don’t have anything to complain about there. The keyboard is just your standard keyboard, so nothing to say about that really.The Wifi adapter however, really sucks, and I mean that. It constantly disconnects from the internet every 1,2 or 3 minutes, I constantly have to unplug it and plug it back in to get the internet to work again. I tried just ignoring it and timing it to see how long it takes to naturally turn back on, but it always seems to turn off for about 3 minutes straight, turns on for 30 seconds then it’s off again. It’s pretty annoying, but I have the internet box in the same room, so I could just use a cord I suppose.The computer is actually kind of small, I thought it looked big in the picture, which is why I didn’t think to get a low profile graphics card, but the regular card(GT1030) still works, even though now I can’t close the case, but anyway, I recommend buying a low profile graphics card, then you got yourself a nice little gaming pc.

Review: I’ve used this computer for about a month. It does exactly what I wanted it for. This a refurbishe computer. Aside from a couple missing case screws and a subtle sleek on the case, one wouldnt know it. It’s quite clean on the inside. No dust. The machine is as described. It has the memory and cpu advertised. Though the wifi is a cheap, but functional, dongle plugged into one of the USB ports. It’s reasonably fast. The supplied keyboard and mouse are cheap but functional. The intalled windows 10 OS had some weird settings. Several windows services were turned off. I had to figuire out which ones they were and turn them back on to make file sharing work accross a lan work. (i.e the “workgroup” stuff) No installation media is supplied. The powersupply is small so this machine is unlikely to work with a gaming video card. This is not a gaming computer. It comsumes very little power taking 17 watts when idle and about 30 watts when busy. It’s also very quiet with the fan almost never turning on. This is not a mini-pc. Is a small desktop about 13 inches square by 3.5 inches thick. I’m using it as a server. It is well suited to that purpose.
