Supermicro SuperChassis 743AC-668B: Whisper-Quiet Tower/4U Chassis for High-Performance Workstations and Servers
Designed for professionals who demand silence without sacrificing power, the Supermicro SuperChassis 743AC-668B blends a refined, scalable chassis with robust cooling and flexible power options. This high-end chassis is engineered to deliver whisper-quiet operation (as low as 28dB) while supporting high-efficiency power supplies and a cooling architecture that keeps critical components running smoothly under load. Whether you’re building a workstation with demanding GPUs or deploying a compact, quiet server in an office or data center, the SC743 family offers a versatile platform that grows with your needs.
- Whisper-quiet operation: The SC743 line is engineered for low-noise performance, making it ideal for quiet office environments, media production suites, or small data centers where acoustic comfort matters as much as raw performance. The chassis minimizes ambient noise while maintaining stable temperatures, so you can focus on work without distraction.
- Flexible, high-efficiency power options: Choose from a range of power supplies (500W, 665W, 865W, 900W, or 1200W) to match your workload. The design emphasizes efficient power delivery, helping to reduce heat generation and energy costs while ensuring stable power for critical components.
- 100% cooling redundancy with high-performance fans: The chassis features a cooling architecture designed for complete redundancy. A set of high-performance fans collaborates to deliver consistent airflow, protecting CPUs, GPUs, and storage from thermal throttling and extending component life even under sustained workloads.
- Versatile form factor: Tower / 4U chassis compatibility: The SC743-series chassis are built to support a broad range of deployment scenarios, from compact towers to 4U configurations. This versatility makes it suitable for professional workstations, high-density compute nodes, or robust home-lab setups needing scalable expansion.
- Expansion-ready and maintenance-friendly: The chassis is designed with modular drive bays, accessible tool-less components, and clear cable routing options to simplify installation, upgrades, and maintenance. This fosters faster deployment and easier routine service, reducing downtime and increasing uptime reliability.

How to Install Supermicro SuperChassis 743AC-668B
- Prepare your components: Gather a compatible motherboard, CPU(s), RAM, storage drives, PCIe expansion cards, and the appropriate power supply from the SC743’s supported options. Verify clearance for GPUs or PCIe devices if you plan a graphics- or compute-intensive build.
- Unbox and inspect: Check the chassis for any transit damage. Remove the side panel and inspect internal mounting points, drive bays, and fan positions to confirm they’re ready for installation.
- Install the motherboard and components: Mount the motherboard on the chassis standoffs, install the CPU(s) and RAM, and secure any heatsinks. If deploying GPUs or PCIe cards, insert them into the appropriate slots and secure with screws or retention hardware as needed.
- Install power supplies and drives: Depending on your configuration, install the selected power supply units (PSUs) in the designated PSU bays, ensuring proper airflow and cable routing. Add storage drives to the drive bays, confirming secure mounting and proper alignment with connectors.
- Connect cooling and cabling: Attach fans and connect all necessary power and data cables. Route cables neatly to promote airflow and easy maintenance, using included tie-downs or cable management features where available.
- Final checks and boot: Double-check all connections, reseat expansion cards if needed, and ensure no cables are interfering with fans. Replace the side panel, power up, and enter the BIOS/UEFI to verify component recognition and initial system health checks.
- Test and optimize: Run a basic stress test or benchmarking suite to confirm thermal behavior and stability under load. If temperatures approach upper limits or fans ramp unexpectedly, adjust fan curves or airflow paths to optimize cooling efficiency.

Excellent Strong Bags - Quick-Tie Feature is Genius!
Scent: Unscented, Size: 21 Count (Pack of 1)
These Glad Quick-Tie trash bags have become my go-to garbage bags for the kitchen. I've been through several boxes now and they consistently perform exceptionally well.
The quick-tie drawstring closure is the standout feature. Instead of fumbling with traditional bag ties or trying to tie knots that never quite work, I just pull the red drawstring tabs and the bag closes securely in seconds. It's so much faster and cleaner, especially when dealing with heavy or messy loads. The closure stays tight and doesn't come undone during transport to the outdoor bin.
Strength is impressive for 30-gallon bags. I regularly fill these to capacity with kitchen waste, food scraps, packaging, and they hold up without tearing or leaking. The plastic feels thick and durable - I haven't had a single tear or puncture even when dealing with sharp edges from cans or rigid packaging. No leaks, no messes on my floor.
The 30-gallon size is perfect for my standard kitchen trash can. The bags fit properly without being too loose or too tight, and there's enough material to fold over the rim for a secure fit. When it's time to change the bag, removal is effortless thanks to the quick-tie system.
Value is decent - while these aren't the cheapest bags on the market, the convenience and reliability make them worth the slight premium. Not having to deal with bag failures, spills, or difficult closures saves time and hassle. The 21-count box lasts me about three weeks with daily use.
I appreciate that Glad has perfected what seems like a simple product. These bags just work reliably every single time. Highly recommend for anyone tired of dealing with inferior trash bags!

Fantastic towels at a great price on subscribe and save
Package Size Name: Family, Size: 286 Count (Pack of 6)
As an oil painter, Viva are the gold standard for wiping brushes and whatever else you need a towel for while painting. I bought them for that purpose. I didn’t count on loving these paper towels for every other paper towel duty in my home.
These paper towels are incredibly hardy, and perform much like a thin cloth towel. They last and last. I can rinse and reuse a towel to clean all the kitchen counters plus clean the stainless steel gas cooktop. All with one section of paper towels. I couldn’t do anything close with any other brand I’ve used.
I love the select a size feature. For quick cleanups, one section is more than adequate. I’ve used one section in my swifter handle when I’m out if swifter cloths (which is always- I never buy those things), and used both sides of the towel to dust mop my wood floors. I use these to dust my home with a little spray wax, cleaned the tires on my car with no towel shredding, and scrubbed the filthy barbecue with bleach cleanser, rinsed it out, and scrubbed some more. These towels are tough yet soft, sturdy and disposable. They are soft enough to use as a napkin, and absorb like crazy.
I buy mine by the case from Amazon subscribe and save every three or four months, and love saving 20% doing so.

Viva is the best and, by usage, the most economical paper towel
Package Size Name: Family, Size: 286 Count (Pack of 6)
Still basically the same Viva. I compared this version with the prior one I still had on hand. This one has a slightly woven vs felted appearance and the side against the roll is slightly rougher or textured, while the outside face is slightly smoother. The inside face looks as if it might leave lint, maybe. Half sheet size is the same and both versions absorbed one ounce of water. Both seemed equally thick, judging by the amount of see-through-ness, both dry and wet. Both seemed equally tough wet. This version clings to the roll less firmly, too.
Viva is the very best AND the least expensive paper towel available based on how long it lasts. It takes weeks to go through a roll, especially if you realize a sheet can be reused to wipe up more than one small mess while you cook and you need many fewer to clean up the big messes. Use one to dry a pot and leave it by the cutting board to wipe up. If you're used to ordinary paper towels, there may be a period of adjustment, but try to take just one sheet instead of the 4 you may think you need; you can always get another. They can scrub an iron skillet or pat dry your food. They make the best handkerchief substitutes, too. One subscribe and save box lasts me about a year.
