PCSP P520 Workstation, Intel Xeon W-2135 3.70GHz 6-Core Processor, 32GB DDR4 RAM, No Graphics, No Hard Drive, No Operating System (Renewed)

I have had this for a few days now and have absolutely no complaints. 1. Unit is very clean inside and out except for a couple exterior scratches which I expected. 2. Very well packed 3. When you get your item there is a card inside to extend your warranty by another 90 days. 4. You might get a CD-ROM also even though it is not stated. It's a bonus so if you don't get one oh well. 5. They give their web address so you can purchase other items for your unit like a proprietary power supply, which they have and is very reasonably priced. I would defiantly buy from this vendor again. I am getting ready to buy more from them, like an extra power supply and the next level up CPU. When I first ordered this I got concerned that I was not going to receive one because they showed "no longer in stock" and was not for sure if they had one for me. I ask customer support about it and with in 2 days I had my new PC(New for me). Dave

I have two of these now, and they work amazing. The only downside is mine didn't have the power cables for newer video cards. So I had to get adapters. But they both arrived in great condition. A custom shipping box and inside and out super clean. Super value for money

As mentioned in the product listing, you'll need some parts to make this function. No drive is included and no graphics adapter as well. You'll need to install your own OS as a result. The box has 2 onboard m2 slots for storage plus 2 disk bays for SSD or HDD. There are 2 PCI 16x slots for graphics and plenty of other ports. All these slots add up to lots of options for whatever purpose you might need a machine. The ram options are great as well. With 8 ram slots, again you can expand as needed. The layout is open and easy to work on with easy swappable parts. Box is a joy to work on. All in all, for this price it's a great starting point to build a solid workstation that can fill many different roles as you add whatever you need to it.

This thing is still a beast despite its age. Lots of PCIE 3 lanes to play with and mine idles around 90w running a bare proxmox 8, 10gb nic, and a GTX 1060 for video out (it was the only card I had laying around). On that note, you *will* need a video card as there (at least on mine) is no on-board video. I also had to reset the bios to get it to recognize my card, so just a heads up. If you have trouble booting, try that first. The box itself is nice and reminds me of other higher-end enterprise servers with a screw-less modular design that makes it super easy to pull out and replace devices, fans, drives, power-supplies, etc. Well, everything but the on-board nvme slots which is difficult to hold and screw down at the same time (no easy peasy flip tab's like more modern mobo). Anyway, if you can find one like this, they make a great home-lab/storage/proxmox host. The fan noise is audible, but could be replaced with something quieter. But for the price, this is hard to beat. Way more bang for the buck than an RPI or similar costing mini-pc's.

Great value for money if you are looking for a powerful/versatile workstation at a reasonable price point. This is the 2nd Lenovo P520 (refurbished) computer I bought and both were in good condition. They have lots of room to expand various specs, drives, graphic cards and other peripherals. This unit will likely perform many tasks better than some PCs bought brand new, doing so while giving you the ability to customize over time and at a much more affordable price. It functions well with both linux and windows.

Computer’s cpu runs like an i7 8700 but only drawing more power if you aren’t worried about power consumption this is for you. Great chassis to upgrade for a budget gaming rig, a GTX 1080 or RTX 2070 would work perfectly with this.

I got this unit to run Turnkey-zoneminder OS. I had a 2Tb SSD and a ASUS RV370SE/TD/128M PCIE 128MB GRAPHIC CARD from 2005. I installed them in boot it up, and it did recognized the bootable USB flash drive and I installed the OS on 2tb SSD. I didn't have to go into the bios to setup anything. I have 8 Reolink 5mp Cameras and a EnGenius EDS5110 camera. I have the zoneminder set to mocord on low resolution and nodect on high resolution linking the low resolution monitors. Altogether I have 18 monitors (9 low resolution and 9 high resolution) running and the CPU usage average out at 31% and memory (32GB) average 76%. I had a i5-4570 PC before this and it crashed after running turnkey-zoneminder for a week. I hope this Xeon W-2135 will hold. Only concern i have is the power supply. It did came with 900W but it is Lenovo proprietary power supply. Can't be replaced with off the shelf power supplies. It came only with 2 SATA power ports and won't be able to add more than 2 SATA drives. This power supply directly connects to the Motherboard, slides in. Unit is very clean, it was used unit but it was clean inside and outside. It was shipped with bubble wrap. When I saw this unit 3 weeks ago in amazon, it was around $131 and when I bought it it was around $141 and the price is keep on going up, just now it is listed for $175! So far, I am happy with the purchase.

The P520 is a nice looking and very capable workstation given it’s age. The motherboard supports PCIE bifurcation, which is specifically why I purchased one for my project. The majority of these P520s come with a 6 core Xeon, which is quite performant, but you can upgrade them (note, most of the CPUs you will find will cost more than the P520). The P520 supports 32gb ECC DIMMs; I have 128gb ram in mine, but it can do 256gb with ease.
