Great performance, but RAM is a bit low
This Dell OptiPlex tower is a solid business machine. The 14th Gen i5-14500 vPro processor is fast and handles multitasking with ease. Boot up and file loading are super quick thanks to the 512GB PCIe SSD, and Windows 11 Pro runs smoothly.My only complaint is the 8GB of DDR5 RAM. For a modern PC, especially with a powerful CPU like this, 8GB feels underpowered. You'll likely need to upgrade to 16GB or 32GB for heavier workloads or running multiple apps at once. Otherwise, build quality is great, and it's quiet and reliable.I recommend it, just plan on adding more RAM.。It has been more than 3 m

ITS OKAY BUT NO CD/DVD DRIVES
THIS ITEM COMES WITH ONE DRIVE CLOUD STORAGE ACTIVE. I DEACTIVATED IT. IT EATS UP TOO MUCH STORAGE TOO QUICKLY FOR FILE BACKUP. I SUGGEST USING AN EXTERNAL HARD DRIVE.

“Finally Built a Trading Setup That Actually Keeps Up”
After comparing multiple systems for trading, I ended up going with the Dell OptiPlex i5-14500 setup with 32GB DDR5 RAM and honestly… this thing has been solid.For running Thinkorswim, TradingView, multiple charts, browser tabs, Discord, news feeds, and my ultrawide + vertical monitor setup all at once, it handles everything smoothly without lag or freezing. The 32GB RAM made a huge difference compared to older systems I’ve used. Charts stay responsive even during fast market movement.Boot times are quick, programs open instantly, and multitasking finally feels effortless instead of like I’m n

Not a bad used desktop for the price
I bought this used desktop from seller: Integrated Recycling Technologies. They packaged it well for shipping. The system booted up quickly and was ready to go. It was like buying a new desktop from Dell. It did NOT include a mouse or keyboard (which I didn’t need anyways), but it did include a power cord.I was looking for a decent, budget-friendly computer that could run Windows 11. This one fits the bill at under $350! It has a quick i7 processor, DDR4 ram, and a SSD. I opted to add more ram since it only comes with 8 GB. Please note that it doesn’t include Wi-Fi or Bluetooth, but you can ea
