This computer was intended to be a "Roblox Gaming Machine" for my 8 year old's birthday. He was using a laptop with a 3500U and Vega 8, and was having some lag. So the idea was to build him a desktop and sell his laptop to recoup some money. Enter the Acer Aspire TC-885-UA91!I purchased the 4-core/4-thread i3-9100 variant, though the case itself is shared between models and is quite compact. This desktop is loaded with features like a dvd-rw drive (with DVD playing software), built-in wifi, etc.As far as memory goes, the motherboard came with a single stick of 8GB DDR4 2666MHz Samsung ram.-- UPGRADE: Threw in a second stick of 8GB ram for 30 bucks, for a total of 16GB (the perfect amount for this build)I was pleasantly surprised to see the SSD is a HP SN520 NVMe m.2, though it does not have a heatsink on it.-- UPGRADE: Added a 5 dollar m.2 ssd heatsink to help extend the life (case doesn't have the best airflow after all).The case itself is nice, it's nothing extravagant but it has a fairly large-sized square of holes in the removable side panel, offering good air flow into the case (being sucked in by the CPU fan). There is a single 3-pin sys_fan header available on the motherboard, as well as the standard mounting location for a 80mm case fan. You will have to purchase this separately because this computer does not come with a case fan -- it only comes with the CPU fan.-- UPGRADE: Added a 10 buck 80mm case fan that has orange LED lights, the holes in the side panel allow you to see in just enough to get that nice view.The power supply leaves a lot to be desired, as it is only rated to 300W and does not include 6-pin or 8-pin power for a graphics card.-- UPGRADE: Took out the 300W and threw in an EVGA 850W modular power supply which fit perfectly. Thanks to replacement PSU being modular, I only connected wiring for things that actually needed power. This would normally cost about a hundred and fifty bucks, but I had this as a spare laying around.If you do upgrade the power supply, and want to continue using your DVD drive, you'll likely need this adapter (I did):https://www.amazon.com/gp/aw/d/B07FK5G2TF?psc=1&ref=ppx_pop_mob_b_asin_titleLast but not least, this isn't a gaming desktop out of the box. If you want to do ANY real gaming, you'll need to add in a graphics card. And remember, to do that, you'll have to also replace the power supply.-- UPGRADE: Bought a RX 5500 XT graphics card and slid it right into the PCIe slot. Plugged in the 8-pin power from my 850W power supply, and booted the computer up.Runs flawlessly. Installed all Windows 10 updates without any issue, installed the Adrenaline 2020 software from AMD for the graphics card, and this thing is handling my son's Roblox games like a champ!To recap the new configuration w/total cost of ~$620:- i3-9100 4-core cpu- 16GB ddr4 ram (+$30)- 512GB NVMe SSD w/heatsink (+5)- VisionTek Radeon RX 5500 XT 4GB GDDR6 graphics card (+$150)- EVGA 850W modular power supply- DVD burner/player (w/power adapter +$10)- 802.11ac wifi, gigabit ethernet, card reader- Windows 10 x64I compared doing a home-built AMD 3200g box, however after you factor in the price of a Windows key, wifi & dvd drive, it ends up being more money and effort. In fact, the i3-9100 is 9% faster than the 3200g and it just made more sense for me to put forth minimal effort, save money and get a better cohesive, streamlined end result (the front of the case is actually pretty slick with its slim DVD drive).I would definitely buy this desktop and replace the components again, it was pretty hassle free. Just need a screwdriver and an hour of your time.
