If I had $250 this Black Friday, I'd spend it on this mouse, keyboard, headset, mic, controller and SSD

Razer DeathAdder Essential | 6,400 DPI | Wired | Right-handed | $49.99 $19.99 at Amazon (save $30)
An absolute no-brainer. My ancient and beloved Microsoft Sidewinder gave up the ghost at a time when I was skint, and I bought this as a stopgap until I could afford something more expensive. Instead it's become my go-to gaming mouse, simply because it's got a great handfeel, perfectly placed buttons and thumb triggers, and an excellent optical sensor. If you need a good mouse then for $20 this is unmissable.

Razer Cynosa Chroma | Membrane | Per-key RGB lighting | $59.99 $29.99 at Amazon (save $30)
Yeah, the snobs will tell you a keyboard has to be mechanical, but tell that to the thousands who have been slaughtered by my membranous boi. I had a Cynosa for years before recently upgrading, which was more thanks to my infant son's fascination with chewing on the Cynosa than any problems with the durability or quality. This is a seriously solid performer and you won't get a better keyboard for $30.

HyperX Cloud Alpha | 50mm drivers | 13Hz–27,000Hz | Closed-back | Wired | $99.99 $54.99 at Amazon (save $45)
Another easy one: Cloud Alpha's not the newest headset on the block but it is one of the best and best-sounding ever made: to the extent Razer even ripped off the smart driver design in its (also excellent) BlackShark V2 range. This is as close as you can get to an expansive open back design in a noise-isolating closed back headset, and at nearly half price is a steal.

HyperX Solocast | Black| $59.99 $34.99 at Amazon (save $25)
If you need a mic and, like me, are too old for all that streaming nonsense, this dinky little fellow offers superb sound quality at a seriously good price. The only downside is that this lacks some features that tend to be standard on the super-fancy alternatives, but if you just want good sound quality from a mic this is hard to beat.

Acer PG241Y | 24-inch | 1080p | VA | 165Hz | $179.99 $119.99 at Amazon (save $60)
This is the cheapest we've seen this Acer screen, and it was already one of the more affordable high refresh rate gaming monitors out there. For an entry-level 1080p screen you won't do better than this price.

Sony DualSense Wireless Controller | The good colors | Bluetooth| $74.99 $49.00 at Amazon (save $26)
Now we are cooking with some serious charcoal. The Playstation DualSense controller is an incredible piece of kit, and once you've felt the haptic feedback on this baby you'll never go back. This feels gorgeous in the hands and many PC games now support its more advanced features: it's also a real premium product that is rarely on-sale, and certainly not at a discount like this. Heck you even get to choose what color you want.

Solidigm P41 Plus | 1TB | PCIe 4.0 | 4,125MB/s reads | 2,950MB/s writes | $89.99 $59.99 at Amazon (save $30)
This is probably because I need to buy an NVMe SSD IRL, and this is a chunky discount on what's already one of the cheaper options out there. The performance is solid rather than exceptional but it will still out-perform any SATA drive and, next to a GPU, an NVMe SSD is the single most affordable upgrade you can make to your PC's overall performance.
