Prebuilt gaming desktops usually force a compromise somewhere, and the Thermaltake LCGS Avalanche i477T makes an interesting case by putting a 360mm all-in-one cooler and a full 2TB NVMe drive into a white ARGB tower. It targets people who want high-refresh 1440p play without opening a case or picking parts.
The spec sheet is unusually balanced for a system in this class: an Intel Core i7-13700KF handles CPU-heavy titles and streaming, while the GeForce RTX 4070 Ti carries the frame rates. You get 32GB of DDR5 running at 5600MT/s and 2TB of NVMe M.2 storage, so there’s no immediate need to upgrade before installing your games.
- Intel Core i7-13700KF CPU Watercooled, Intel Z790 Chipset, 32GB DDR5 5600MT/s RGB, 2TB NVMe M.2, WiFi
- NVIDIA GeForce RTX 4070 Ti, 3x Display Port/1x HDMI
- Closed Loop Liquid Cooling with 360mm Radiator
Built on an Intel Z790 board with Wi-Fi and shipping with Windows 10 Home, it arrives assembled, cabled, and ready for a monitor. Owner feedback leans positive on speed and acoustics, although a smaller group reports hardware failures within the first few months.
Bottom Line
This is a sensible pick if you want a liquid cooled gaming PC with room to grow and no assembly work in front of you.
Register the warranty when it arrives and stress-test it early. Do that, and you’ll have a machine that handles 1440p at high settings for years.

Thermaltake’s LCGS line uses its own chassis, fans, and coolers, so the build feels like a coherent system rather than a collection of unrelated parts. The model number, D3AV-Z790-47T-LCS, identifies the 2023 revision.
NVIDIA GeForce RTX 4070 Ti Graphics Performance
The 12GB RTX 4070 Ti sits comfortably in the 1440p high-refresh bracket, delivering triple-digit frame rates in most competitive titles and 60 to 90 fps in demanding single-player games at high settings.
DLSS 3 with Frame Generation extends its usefulness quite a bit. Ray-traced titles that would otherwise crawl at native 4K become playable once upscaling is enabled, and one owner reported running Baldur’s Gate 3 on a 49-inch 1440p ultrawide OLED at maximum settings without trouble.
Display output covers three DisplayPort connectors and one HDMI, so multi-monitor setups work without adapters. If you’re comparing generational value, the gap over something like the ASUS Dual GeForce RTX 4060 is substantial at higher resolutions.
Intel Core i7-13700KF and 360mm Liquid Cooling
Sixteen cores, split between eight performance and eight efficient cores, give the i7-13700KF enough headroom for simulation-heavy games, encoding, and background streaming without frame pacing suffering.
The KF designation means there’s no integrated graphics, which is fine here since the discrete card handles all output. It does mean troubleshooting a GPU fault requires a spare card, though.
Thermaltake pairs the chip with a TT ARGB 360mm radiator, and that surface area matters for a processor that pulls significant power under sustained all-core loads. Owners consistently describe the system as quiet during gaming. If you want to see how a similar radiator performs on its own, the ID-Cooling FX360 INF offers a useful reference point for 360mm acoustics and thermals.
32GB DDR5 Memory and 2TB NVMe Storage
Thirty-two gigabytes of DDR5 at 5600MT/s is the right amount for this class of machine, leaving headroom for modded games, virtual machines, or a browser full of tabs alongside a running title.
Two of the four DIMM slots stay populated, and the board accepts up to 128GB total if your workload ever demands it. The modules also carry RGB lighting that ties into the case theme.
Storage is where the configuration stands out. A 2TB NVMe M.2 drive means roughly 20 modern AAA installs before you think about expansion, with sequential speeds that make SATA feel dated. Anyone shopping for additional capacity later will find the best NVMe SSD options drop into the remaining M.2 slots.
White ARGB Case, Ports, and Wi-Fi Connectivity
The white chassis with tempered glass and addressable RGB fans looks clean rather than gaudy, while the PSU cover keeps cable clutter out of sight.
Front I/O is where expectations should be calibrated: one USB 3.0 port, two USB 2.0 ports, plus separate headphone and microphone jacks. That USB 2.0 allocation feels dated for a 2023 system, though the rear panel adds more connectivity.
Wi-Fi comes built into the Z790 board, so wireless connectivity works out of the box with no PCIe card needed. Owners report clean connections without much driver hunting. The filtered ventilation and vertical side-mount radiator support give you options if you later add a second loop.
Setup Experience and Upgrade Potential
Unboxing to desktop takes about fifteen minutes. The machine arrives well packaged, cabled internally, and with Windows already installed.
One buyer noted needing a small case modification to route a DisplayPort cable comfortably on a large ultrawide, so check clearance behind the tower if your desk sits tight against a wall.
Upgrade room is real. The standard ATX layout accepts graphics cards up to 360mm, two DIMM slots stay free, and additional M.2 storage slots remain open. The Z790 socket also supports 14th Gen Intel chips, giving you one more CPU generation without a board swap. Compared with a more compact build like the Thermaltake LCGS Glacier 460, serviceability here is refreshingly straightforward.
Pros and Cons
Pros
- Strong 1440p performance from the RTX 4070 Ti with DLSS 3 support
- 360mm AIO keeps the i7-13700KF cool and audibly quiet under load
- 2TB NVMe storage removes the usual prebuilt capacity squeeze
- 32GB DDR5 5600MT/s means no day-one memory upgrade
- Built-in Wi-Fi and three DisplayPort outputs for multi-monitor setups
- Standard ATX internals make future upgrades practical
Cons
- Front panel leans on USB 2.0 ports
- Ships with Windows 10 Home rather than a newer OS build
- One-year manufacturer warranty is shorter than some competitors offer
- Several owners reported motherboard or power delivery failures within months
- No integrated graphics on the KF chip complicates GPU troubleshooting
Customer Reviews and Reliability Feedback
Sentiment splits along a clear line: buyers who received a healthy unit are enthusiastic, while a minority encountered component failures inside the first six months.
What Owners Praise
Speed and quiet operation dominate the positive feedback. One owner reported five trouble-free months and noticeably faster daily work, while another said the fans stayed inaudible during maximum-settings gaming even without headphones.
Packaging and setup draw repeated compliments. Buyers describe the machine as working immediately out of the box, with the white ARGB aesthetic cited as a genuine selling point rather than an afterthought.
Reported Issues to Consider
The failure reports are specific and worth weighing. One buyer had a motherboard fail within 30 days and returned it for a refund; another described the system refusing to power on after roughly a month, with a suspected PSU fault.
A third reported a total failure around five months in, complicated by an extended warranty that wouldn’t engage until the manufacturer coverage ran out. Test the machine hard during the return window.
Conclusion
The Avalanche i477T earns its place if you want 1440p high-refresh gaming without sourcing parts, and the 2TB drive plus 32GB of DDR5 help the configuration stay relevant longer than most prebuilts at this tier.
Weigh the one-year warranty against the failure reports before buying. Run demanding titles, a memory test, and a sustained CPU load within the Amazon return window so any weak component surfaces while you still have full recourse.
Anyone comparing this against other assembled systems should also look at the CyberPowerPC Gamer Supreme Liquid Cool for a sense of how competing configurations allocate budget between CPU, GPU, and cooling.
